Your bullrush and rip would be you power moves with the swim and spin as the finesse so the could map it where if you tap square it would perform a rip but if you held it down you would use a straight bull rush, etc if they wanted to keep the button system. I just wish they gave us more control.
And I hate that its basically you either beat the Oline or get stone walled. How often do you see a DL get a good jump and even if they dont get to the QB they at least force him off the spot and make him have to move.
