Small Forward Sprinting Problem

This may sound weird, but in my game i just cannot sprint with small forwards. its been like this since i got the game and when i hold down the turbo/sprint button all players go into the sprinting animation and run quickly, except all small forwards just sorta crouch down with one arm out and hardly even jog. this is really frustrating because i tend to play as teams with small forwards as their stars, like the cavs, boston or seattle. i find it very hard to get to the hoop with a guy like Rashard Lewis, (with quickness and speed ratings both in the high 70s ) because he runs like f***in oliver miller. any one have any ideas on how to fix this or have the same problem?

also, does anybody know how to lessen the effect/or "cure" the annoyance of the computer catching up so easily especially on fast breaks, any help would be greatly appreciated

oh i forgot to say, the small forwards sprint normally in practice mode.
