I think Cam can hit big plays if the hole is there - he's got really good speed. But he has limited change of direction once he gets going - so it's hard for him to create for himself. And he'll take on contact, but he doesn't get many yds after contact.
This is definitely just my opinion, but I think since people crowned him too early after the GT & VT games they've talked themselves into looking past what's right there.
Like that he was 9 for 14 yds & a lost fumble after the GT/VT games. Then he got outplayed by DeeJay last Spring but people had already decided Cam was going to be the starter. And then DeeJay outplayed him last year. Cam has been 4.8 ypc since the VT game, and hasn't made big plays receiving game either. And most of his big games have come against bad defenses.
Again, Cam is good - but once fans crown him they'll make excuses for some pretty easily seen red flags. I just think his ceiling is lower than most.
