I'm a back seat player. I will kick the ball and then stand right at the back on the middle of the TD line where I can shout useful advice and commands to the other players (like 'BRAAAIINNS!'). I will only move away again if the opposing team has the ball within my movement range (ie, is near to scoring), in which case I will move to man mark/blitz the ball carrier or generally join in and do my best to stop a TD"
