Thinking Outside the Box

“It never occurred to them that, if everyone had to think outside the box, maybe it was the box that needed fixing” [Gladwell, What the Dog Saw]

When picking a fantasy team, like when trying to win anything, most participants will search for an ‘edge’ or secret formula to give them a jump-start over their opponents. This may take the form of relying on industry knowledge (“a friend of mine is a scout at Spurs and he assures me Assou Ekotto will retain his starting LB position from last season”), trend analysis (“Rooney scores 69% of his goals against bottom half teams”) or historical performance (“high price midfielders always out deliver their expensive forward counterparts”).  This quest for more information works on the assumption that the common ‘knowledge’ is at best limited and at worst incorrect.

How true is this though? In NFL fantasy we are told to draft running backs in the first round, in baseball anyone who can deliver speed and power is a sure fire early pick and the EPL game is no different in giving us several age old adages upon which we base our team. One of them that interested me is how reliable a measure of success is the number of playing minutes a player generates in the season. Many – including this blog – will often praise the virtues of the reliable player will who play 90 minutes each week and while not win you the league, will never lose one either.  Let’s take a look at the numbers:

Forwards
The correlation between forward minutes and points is strong (0.772) which is in line with common sense – if you don’t play you will struggle to achieve the main aim of a forward: score goals. What is also worth noting is the strong correlation (0.726) between points scored and player value. 


 This suggests that bargains are hard to come by when it comes to strikers and only a couple of players can be described as anomalous outliers last year (Bent, Tevez and Rodallega all outperformed their value). When it comes to minutes played, the four best ‘overachievers’ are the big four of Drogba, Rooney, Tevez and Torres (to be expected given their individual and team talent).

You can summarize this position as ‘you get what you pay for’. It is going against recent history to expect to find a forward equivalent of a 2008/09 Stephen Ireland or a 2009/10 James Milner. Players like Amr Zaki 2008/09 have done it to a degree but failed to keep it up for a whole season, instead leaving you to try and capture lightning in a bottle.

In summary, the data from last year underlines the need to pay for big name strikers. A look over the message boards at Fantasy Football Scout suggests that many consider this to be an anomaly and are returning to the big midfield names, but until I see otherwise, I will be paying a premium for strikers who can be relied upon not just for minutes but also for goals.

Midfield
The correlation between midfield points and minutes is much weaker than with forwards, and indeed at 0.535 we can conclude that there is only a weak linkage. 


Admittedly the sample size is quite a lot larger than forwards but still the number of both over and underachievers is noticeable. This is somewhat of an eye opener to me as I have often stuck with midfielders through baron patches on the basis that they are guaranteed to play – which I thought was a useful measure of overall success.  In fact, you are better chasing points a bit and trying to find the form player rather than stubbornly sticking with the player who just isn’t delivering the goods.

The linkage between points and value is once again relatively strong at 0.701 showing once again that you get what you pay for.  Plenty of outliers exist though and this line of best fit is somewhat skewed up by the outstanding returns delivered by Lampard and Fabregas.


 The data shows that while, of course, the top players will always usually deliver good returns, there is value to be had elsewhere. Also, relying merely on a player getting consistent minutes is not enough to guarantee good returns in the future.

Defenders
The key lesson here is the lack of correlation between value and points – standing at just 0.559. 


Thinking about this for a second, this suggests that all those United, Chelsea and Liverpool players are overvalued and you should continue to pursue players from team such as Fulham and Villa last season. This makes sense due to there being 2 ways to ‘beat the market’ when it comes to defenders. Firstly, a team’s players are undervalued, like with Birmingham last season, whose players could mostly be picked up for 4.5m or less. The second is a player on a premium team who is valued significantly below his teammates but still gets the same access to clean sheets. These are hard to find right away but much success has been enjoyed in previous seasons with players like Johny Evans, Armand Traore, Martin Skrtel and Roy Caroll who have all gained significant runs in top teams despite costing several million less than their teammates.

Now, be careful here, as we are not saying the top defenders to not deliver at all. Indeed, of the top 10 leaders in points only Jody Craddock who scored an unlikely 5 goals was available at a low price. What we are saying though is that, comparatively speaking, there is better value to be found lower down the price lists than with forwards and midfielders.

Goalkeepers
Not much to say about value against points as there is not a strong correlation (0.619) and the best points delivered by 4m and 4.5m players comes close to that delivered by the most expensive players. 


I emphasized last season that you should not pay for a goalkeeper – instead relying on a rotation system – but even if you simply played someone like Sorensen or Hart every week you were still rewarded with much better value and only 20 points less over the whole season.

As you would expect the correlation between minutes and points is extremely strong but there isn’t much fantasy advice to gain here other than make sure your ‘keepers are playing!

I am sticking with the rotation strategy for this season, and I will post shortly who I think complement each other well to avoid having to play unfavourable matchups as often as possible. 

To conclude then, it seems that the old adage of getting 'reliable minutes' is not always a useful measure of fantasy success and we should look for other means of determining value. While it seems obvious to say that price dictates performance, we can see that this holds truer for forwards than for other positions and so it seems wise to once again spend money up front, so long as you feel the EPL forwards will enjoy another good season.

The Prisoner's Dilemma

With Cristiano Ronaldo due to return from injury tomorrow against Villareal, any sensible fantasy player must contemplate the possibility of bringing him into their team. Last season Ronaldo was simply incredible and anyone wishing to compete had to have him in their ranks (I was one of the stupid few who kept insisting he couldn't continue his form and I duly finished 7th in the league). As incredible as the 31 goals were last year, whats almost as fantastic was the fact that the prior year he'd accrued 244 points, only 39 less than last year's historical year. This leads me to believe he can ,and probably will, score along those line this year (minus the points for the 3 games missed already).

However, at 14m he is 2.6m more than the next midfielder (Gerrard) and 2m more than any other player (Torres).

Deco currently leads midfielders with 31 points but is only 7th in points per million spent (PPMS) at 0.816 (using his current value of 9.5m). Here are the top PPMS ratings so far this season in the midfield:


Granted, with all due respect, it is unlikely that Stephen Ireland and Rory Delap will continue at this pace for a whole season a player like Arteta or Deco may well do so and we'd expect Lampard to get even better from his current position. At Arteta's PPMS Ronaldo would have to notch 12.8 points
every week in order to represent as good value for money. At Deco's rate, 11.4 points per week. Even at Lampard's rate down in 12th position he'd need to accrue 8.5 every week.

Last year Ronaldo cost 12m and scored 283 points in 2746 minutes, the equivalent of 30.5 games. This gives him a PPMS of 0.773, below the likes of Deco so far this season. To maintain this rate he would need to score 10.8 points per week (the equivalent of say a goal, an assist and a couple of bonus points).

The Dilemma
.

So does the evidence suggest we should stay away from Ronaldo this season? Absolutely. But here is the dilemma, and the wild card that messes all of the above up: the captaincy. Whilst valid to say you'd prefer to save 3m and take Lampard using it to get, say Ricardo Carvalho rather than Andy O'Brien, the problem is that even if these two combined score as many as Ronaldo and O'Brien, you can only have one captain. And you can be sure that most people who fork out the 14m on Ronaldo will tattoo that armband to his arm for the rest of the season.

We are faced with the classic prisoner's dilemma situation. If we all could just agree to not take Ronaldo then we could carry on as is now with well balanced teams and good squads. However, no one can risk being the one guy who doesn't get on the bandwagon before he smashes four past Stoke (and these games will inevitably happen) so we all are forced into shoe-horning him into our teams.

I think the league may well be won and lost on how we treat Ronaldo and it'll be a brave (or foolish) man who leaves him out again. That being said, for me to free up enough cash to get him for Lampard I'd have to use all my bank balance (1.4m) and free up a further 1.6m by, say, trading down from Ashley Young to Aaron Lennon or Owen Hargreaves. Or I could lose Gael Clichy and replace him with Gretar Steinnson. At the moment I am unwilling to make such trades but upcoming home games for Ronaldo against West Brom, West Ham, Stoke and Hull I could well be using all my strength to try and close the stable door as the horse bolts into the distance.
