Championship Week 9: A midweek quickie

Just a quick post today with the next round of Championship games being played midweek.
Here's the real life table as it stands after Saturday and Sunday's games:

23 Fulham 9 1 1 7 8 20 -12 4
24 Blackpool 9 0 2 7 4 13 -9 2

Notable results over the weekend included Fulham's first league win of the season over Birmingham and the six goal thriller between Reading and Wolves.
However my pick of the last round was Blackpool's 3-1 home defeat to Norwich.
This result out of any shows that when your luck is out, it really is out.
The Seasiders took the lead against probably the best team in the division and then got turned-around by an own goal and a massive deflection.
The poor defending which led to the third Norwich goal probably shows a combination of lack of skill and sheer dejection kicking in.
I'm really beginning to feel sorry for Blackpool - fans, players manager. Admittedly their shot share has tailed off in recent weeks, but this really is a brutal run of luck.

2 Nott'm Forest 120 112 0.517
3 Wolves 125 107 0.539
4 Watford 126 153 0.452
5 Ipswich 127 140 0.476
6 Derby 128 124 0.508
7 Middlesbrough 151 77 0.662
8 Charlton 88 131 0.402
9 Sheffield Weds 128 107 0.545
10 Blackburn 140 125 0.528
11 Reading 98 123 0.443
12 Brentford 120 127 0.486
13 Leeds 79 154 0.339
14 Bournemouth 136 111 0.551
15 Cardiff 97 140 0.409

20 Huddersfield 133 119 0.528
21 Birmingham 114 145 0.44
22 Bolton 113 161 0.412
23 Fulham 117 117 0.5
24 Blackpool 102 132 0.436

Looking forward to this week's games, and there are a few that are probably worth looking out for from an analytics view.
Brighton v Cardiff is interesting, because despite being two bottom half teams, the Seagulls are second in shot share (Corsi/TSR), second in shots on target share... and third worst in luck (PDO).
Cardiff meanwhile have improved shot shares slightly over the last couple of games and are now eighth in shots on target share, with a just below average PDO score.
So it could be very interesting to see how that one plays out.



Position Team shots on target for total shots on target against total Shots on target share
1 Norwich 53 36 0.596
2 Nott'm Forest 37 36 0.507

12 Brentford 43 43 0.5
13 Leeds 26 44 0.372

22 Bolton 34 54 0.386
23 Fulham 37 44 0.457
24 Blackpool 28 38 0.424

The bottom three clash between Fulham and Boloton shouldn't even be close looking at the underlying numbers, but again, PDO is doing a big bad job on Fulham. I keep saying the London side are due a turn in luck, maybe its starting with that win on the weekend.

Derby vs Bournemouth is another that suggests an interesting match-up. Derby are still much fancied, but Bournemouth's numbers really are very good indeed. This could be a case of score effects here, but having watched a couple of the Cherries' games they certainly seem the genuine article to me.
Its noticable that every team above Bournemouth in the table has a higher PDO score. Again, as that starts to settle down a bit more we should see the south coast side move up the table and they could be an outside bet for the playoffs or even promotion.


Position Team Shooting % For Save % PDO
1 Norwich 37.73 77.78 115.5
2 Nott'm Forest 45.96 80.55 126.51

23 Fulham 21.62 54.55 76.17
24 Blackpool 14.29 65.8 80.09


And finally I really do fear for the health of Joe Lewis in the Blackpool goal. It's just about the worst week he could expect. First Norwich (most shots taken in the league), then Middlesbrough (second most shots taken). If form (and luck) stays true, then it could be a massacre at Bloomfield Road.
However stranger things have happened in football than a rock bottom team seeing its luck turn against one of the top sides.

Championship Week 8: Moving day - tracking the early season ups and downs

The Saturday (or third day more generally) of major golf tournaments is commonly known as "Moving day".
So with the greatest golf tournament of all on-going (the Ryder Cup, of course), TOSTM has chosen today to look back at some of those who have made noticable moves either up or down the table from the early weeks.

Let's start with the table as it stands after eight rounds of matches:


Position Team Played Won Drawn Lost Goals For Goals Against Goal Difference Points
1 Nottingham Forest 8 5 3 0 17 7 10 18
2 Norwich 8 5 2 1 17 7 10 17

4 Watford 8 5 1 2 15 8 7 16
5 Middlesbrough 8 5 0 3 13 7 6 15

23 Blackpool 8 0 2 6 3 10 -7 2
24 Fulham 8 0 1 7 6 19 -13 1


The most noticable mover is probably Leeds United. After a horror start to the season which I wrote about in week four and which earned Dave Hockaday the sack, all is now well and rosy at Elland Road with Leeds safely out of danger in mid-table and no hint of problems on the pitch.
And just two points off a play-off place the team really has a shot at going for promotion too.
Not so fast.

Back in week four Leeds had a 31.4% share of all shots (Corsi/TSR). After week eight Leeds has.... 33.7% of all shots.
So what explains the massive rise up the table?
Well the majority of it can be put down to our good old friend PDO. In week four Leeds had a way below average PDO of 71.66. After week eight that's now a bouyant 114.06.
However, we know PDO is not really sustainable over the long term so there's some warning signs there, particularly with the shot share not significantly improving.

There is one encouraging sign: in week five (the first time I have these figures for) Leeds had 30.3% of the shots on target - pretty close to its all shots share.
In week eight, that number has increased to 40.4%.

Whether that number is sustainable without a reciprocal improvement in all shots I'm not sure.
But I would not be counting any chickens just yet, Leeds fans.

Also, once again, poor Dave Hockaday. Given another couple of weeks this PDO bounce could have been his and he'd still be in gainful employment having "riden out the storm".
but still, if these underlying numbers don't change much I suspect this might be the high water mark for Leeds this season.



Position Team Shots for total Shots against total Corsi/TSR
1 Nott'm Forest 106 100 0.515
2 Norwich 153 99 0.607
3 Wolves 115 94 0.55
4 Watford 113 123 0.479
5 Middlesbrough 142 72 0.664
6 Sheffield Weds 118 93 0.559
7 Ipswich 112 116 0.491
8 Charlton 83 122 0.405
9 Derby 112 115 0.493
10 Blackburn 110 112 0.495
11 Reading 85 113 0.429
12 Leeds 66 130 0.337
13 Millwall 117 99 0.542
14 Brentford 96 114 0.457
15 Bournemouth 119 100 0.543
16 Cardiff 83 130 0.39
17 Wigan 101 83 0.549
18 Brighton 135 78 0.634

22 Huddersfield 122 111 0.524
23 Blackpool 92 117 0.44
24 Fulham 104 108 0.491


Reading and Ipswich

I mentioned Reading last week, so will avoid going into too much detail about the Royals. But Ipswich's season has prgressed very similarly to Reading's so far.
Four weeks in the clubs were tied on four points well in the lower half of the table.
Now Ipswich is joint seventh on 14 points with Reading tied for eleventh on 13 points.

Both teams have seen their shot share fall, but their PDO rise from below 100 to well over it.
In fact, Ipswich now has less than half the shots in each game on average, with Reading seemingly slipping further away from parity each week. 
However the shots on target share is a far happier one for Ipswich than Reading.

If forced to, I know which team I'd be putting some money on to retain its position throughout the season.


Position Team shots on target for total shots on target against total Shots on target share
1 Nott'm Forest 36 34 0.514
2 Norwich 47 30 0.61
3 Wolves 30 23 0.566
4 Watford 38 35 0.521
5 Middlesbrough 40 20 0.667
6 Sheffield Weds 32 23 0.582
7 Ipswich 35 34 0.507
8 Charlton 28 36 0.438
9 Derby 42 44 0.488
10 Blackburn 43 43 0.5

21 Bolton 32 47 0.405
22 Huddersfield 40 41 0.494
23 Blackpool 22 32 0.407
24 Fulham 29 41 0.414


Middlesbrough

In week six I singled out Brighton and Middlesbrough as teams to watch to move up the table when their PDO scores regressed from subterranean levels, as the underlying numbers were pretty good.
Well, we're still waiting for the Brighton bounce, but Middlesbrough duly obliged over the next two games and are now sitting pretty in fifth place, still with top class shot share numbers.
Which means trouble for those teams around them.

1 Nott'm Forest 47.23 79.41 126.64

23 Blackpool 13.64 68.76 82.4
24 Fulham 20.69 53.65 74.35


Huddersfield

We also have a new most cursed team.
Yes the Terriers have taken over from Blackpool and Fulham.
True they haven't moved that much in the table, largely because their luck has just got worse.
With a PDO of 73.62 they are just having a norredous time at the moment, despite being a positive shot share team.
Of course some of that may be down ot score effects, but you would have to think it will turn around at some point.
Only Blackpool has a worse scoring rate and Fulham a worse save figure.
Poor Huddersfield.

23 Blackpool 0.44 82.4 0.407
24 Fulham 0.491 74.35 0.414


Finally, Cardiff
Cardiff has been one of the other big movers so far in this early season.
But I've covered the ups and (mostly) downs quite a bit here, so I'll leave that for the rest of the day.

As ever, play around with the tables and see what other trends you can spot.
Comments and suggestions always welcome and when life calms down I've got a couple of extra posts to hopefully put up too.

Championship Week 7: Reading and Charlton – brothers in fancystats

Last time around I looked at Middlesbrough and Brighton, two teams seemingly cursed by the football gods. So this time let’s look at those teams apparently in the Almighty’s good books - Reading and Charlton.
As we can see from the early season real life table, both teams are sitting nicely in the top six on 13 points – one win away from Norwich in second.
But there’s a clue even in this table that these positions might not be fully reflective of the clubs’ performances already.

24 Fulham 7 0 1 6 6 18 -12 1


Charlton have a goal difference of +3, while Reading’s is just +1.
Derby (+5), Sheffield Wednesday (+3) and Ipswich (+3) all have goal differences equal to or better than Charlton’s, while teams as far down as Bournemouth and Wigan (in 15th and 16th respectively) are equal to Reading’s score.
This certainly isn’t definite proof that these teams are currently sitting above performance levels, but it gives a hint that we should be scrutinising them.
So let’s do that and have a look at the deeper stats.

Well we can see that the indications from the goal difference are right in this case.
And it’s remarkable just how similar these teams are: both are well under 50% shot share (Corsi/TSR) and both have high PDO (luck) scores driven largely by sky high shooting %s - first and third in the league.
And both are wildly unsustainable in the long term one would expect.
Going down to the raw data it is amazing how similar they are – Charlton have taken 70 shots, conceded 99, with Reading taking 74 and allowing 97.
If we want to see which of these team’s success is more sustainable, we need to find a bigger difference between them than the odd shot here or there.
Well three points of PDO late in the season would be a more significant margin later on in the season, but in these early days it can be as little as the difference of one goal scored, or one extra save made.
However, the shots on target tell a different story.

Both teams have a variation of about 0.04 between their shot share and shots on target share scores – only in opposite directions, producing a 0.075 difference in Charlton’s favour.
Sure that might not seem like much, but continued at the same rate, that would mean an extra 7.5 shots on target per 100 taken.
And if we extrapolate that at league average shooting rates (31%) – we can see that Charlton would expect to score around 2.3 more goals than Reading per 100 shots taken.
Over the course of a season, that can certainly prove the difference between being in the playoffs or just outside, or in the relegation zone or not.
However the big take away from Charlton and Reading is that neither team has pretty numbers right now.
Sure, score effects will likely be playing their part, but a near 50% shooting level just isn’t sustainable, and sooner or later the PDO score will cool off.
Whether this pair can adapt when they do will be the important question, or it could be a very bumpy ride.

Ouch

Speaking of bumpy rides, I’m really beginning to feel very sorry for Felix Magath at Fulham.
Despite scoring three goals away at the league leaders he still gets burned by PDO with Forest scoring on all five shots on target.
Even Ross McCormack’s first league goals for the club couldn’t help him out.
It really is painful to watch at the moment. I’ve not had time to look at the goals Fulham conceded to see what was going on there, but it seems pretty harsh to ship five goals on five shots on target, even if one was a penalty.
I’m quite frankly amazed that Fulham owner/chairman Shahid Khan has stuck by Magath so long. Either he appreciates the team isn’t getting outplayed (a 50.3% shot share shows that) and expects the luck (72.2 PDO) to turn around at some point, or he’s simply not ready to write-off his investment in Magath (personally and financially) yet.
Either way I tip my hat to him for waiting it out.

[UPDATE: Apologies but by the time I published this post Khan had actually sacked Magath. It's been an incredibly hectic week for me and I didn't get a chance to double check it before publishing. As I wrote, I was surprised Magath lasted as long as he did in this age of short-term managers, but would have liked to see him given a while longer. So who will be the lucky receipient of Fulham's PDO rebound (when it does)?]

Goodbye

In contrast Ole Gunnar Solskjaer’s departure from Cardiff was probably fairly deserved through both statistical analysis and on the pitch performances.
More on this later, but the Bluebirds had been constantly outplayed all season with only a highly inflated share of the shots on target and slightly elevated PDO keeping them above water.
Once the PDO started to fall and the share of all shots (Corsi/TSR) continued dropping it really was time for him to go.
And for those who watched the final few games of Solskjaer’s reign, they will have been all that was needed to seal his fate.
