I remember when I posted that Oregon vs USC game where Barner had like 350 yards and 5 tds and people told me it was just the system and he looked slow. lol
And like rayzor said, Barner is gonna be a chess piece. I don't think he can pass block very well yet.
I'm probably in the minority here, but i don't even think he needs to be much of a blocker. i mean it would be nice to have more help there, esp. considering how ugly the big uglies are so far, but i think that he's gonna be someone that defenses always have to account for everytime he's on the field. there's gonna have to be a spy put on him him anytime he's on the field because there are so many ways he could be used and because of the damage he'd be able to do so quickly after touching the ball. his presence on the field will help cam out because it forces attention away from him. basically it takes a potential pass rusher out of the equation.
of course all of that depends on his usage and his ability to not suck when he's on the field. I'm just seeing a lot of outside of the box potential with this guy.
