The fullback dive is not a staple of anyone's offense in the NFL. Most fullbacks get a carry or so per game, if that.
But if it's a money play, how is it not cheese? Didn't you just say you keep FG block as an audible to stop others from running FB dive? How is it not cheese if it takes an 11 man rush to stop?
I hope sometime in the near future Madden gets to the point where football strategy trumps video game strategy.
