This trick works with any kicker. When you are kicking off, select "Onside Kick" 
when the return team is switching formation. When they are set, take the power 
bar all the way to the top, but do not select it. Bring it all the way down so 
that the power is at 31. Next, make your accuracy 97 to 99. The ball will hit 
the ground and go up straight up in the air every time. Have one of your players 
that is close to the ball sprint toward it. This makes all your players follow, 
and you will usually get it.
