Yea but the majority of the slow animations are on defense.

So while offensive players might get a boost in speed, so does the Dline's pass rush speed.

So instead of the QB having 5 seconds, he may have 3 now, even if within that 3 seconds, the WR gets down field quicker.
I'd rather force the player to react faster on offense than giving him time. (try playing on slow and see how easy it is to pass the ball)

In the OP, Lbz was talking about online play. Legend forces both player's blocking sliders to go down. If you want the same results offline, you might have to manually slide the CPU's sliders down.
