i like all but one of the ideas so far, and thats the 'blamed for when the tackled player is the last assist' one.
i dont think that would work, quite a few times iv hit one of their players charging a cross, only for the ball to roll into the path of another of their players, who shoots/vollies it towards the goal. its more luck than the defenders fault.
also another point.. why have 2 people in the 'best keeper' section, surely one is enough O_o
