It'll be easier to see the running lanes (essentially makes the linemen block better) and supposedly you don't get taken down by so many freak spurts of wind.
As far as awareness though, it definitely makes a player better if you are usering them. Pretty much the same could be said for most stats --- "There is no I in team, but there is a me in team. If you jumble up the letters."
Awareness does a lot too for their overalls and overalls help a lot in the game. --- Intel i5 2500k+on FRIO|8GB G.Skill RipJaws|VelociRaptor, WD Fals|AsRock z68 Extreme 4 G3 |Sapphire 2GB 6970|Corsair 520W PSU|Corsair 500R & K90|Win 7 Pro 64
