Raising their game or feasting on the weak (or, which teams do players do well against)

However good a player projection system is, it will always have certain assumptions built in which require some judgement on behalf of the model's creator. This might include how much weight to put on recent games versus historic data or how much to regress team or player conversion rates back to a league or historic average. One such assumption I do not currently factor into my own model is which kind of games a particularly player performs well in.

They've scored just two goals less than Man United, four more than Arsenal, five more than Chelsea and ten ...
