on offense learn the routes that work, like that cant get inted but what helps most is that when nothing is open, throw the ball away (hold c and then throw). or you can try rolling out every once in a while and then you could get in better position on WR against the defensive player.
try to shift the line so it spreads, becasue a lot of people dont run up the middle anymore...
try the cover 2 and then use bump and run
thats all i got right now i guess id have to play you to find out more and i will later in the league
