Easy fumbles
Do an onsides kick, then do a hard hit (L1 + X). They will fumble about 75% of the time. If it is raining or snowing, there is about an 80% chance they will fumble. This only works if you do hard hits.
Easy sacks
When at the line, take your LB and put him on the left or right side and blitz in. Press L1 + X to do a hard hit on the QB.
Easy turnovers
Blitz in with your LB and try to do a hard hit (L1 + X). If you miss the sack and the QB throws the ball, press Circle immediately when you see him throw it. This will switch players and go to the closest person to the ball on your team. Then, tackle the intended receiver before he gets the ball and it will be an incomplete pass.
