Skip "Measuring"
When you run and almost get a first down. Like if your on 1st and 10 and you run 10 yards when the "measuring" bar comes up just press X and you will skip it. There is no guaruntee if you will get a first down on the cheat or not but usually you do about 75% of the time.

Sacked
Before the halftime menu comes press X and when you resume the game. Whenever your QB and your opponents QB goes for a pass, he will be sacked all the time.
