Don't be afraid to play like a pussy.
If ur opponent is better than you, don't be afraid to run cheese plays and run the ball and chew clock.
I heard this in the MCS last week where one player (I think it was MrFootball88 but I don't rememebr) diagnosed a defence that his opponent was running and knew that it was easily run over, and so he ran it. The announcers talked about how he was the type of player that doesn't care about what others think of him and will do whatever it takes to win.
So play like you don't care about how other people think of you and how ur opponent thinks of you.
