here it is: play a game with cpu assistance on, and then rematch the same game with cpu ass off. I noticed that it's impossible, at least by my way of playing live 2003, to play a decent game with assistance off. First, because it's impossible to defense against cpu, and then because your team mates seem to be dumb, they don't follow the fastbreaks as they do with assistance on, don't defense at all...
So i suggest to all who have difficulties in playing this game to turn the cpu assistance on. The games will be closer and the gameplay much better.
