Yeah ... the impact/collisions/whatever-you-want-to-call-it is the worst thing about this game.
Sure, I get super-tilted early on ... my bad.
But, the amount of times the slightest of nudges means my player stumbles, gifting possession to my opponent, is ridiculous! Combine this with the times I get blatantly fouled - in the box or wherever - because maybe, just maybe his boot laces brushed the ball before half-killing my player, is driving my nuts.
