I've heard that Cam has put on a lot of size. Want to know my source? Well... I usually don't share but... it was an 8th grader in Beatrice that saw him over the holidays and said, "He's HUGE!"
Honestly though, Cam IS going to contribute soon. Frost has said and it's true, he's just a freak athlete for his size. Obviously center is a position where someone really needs to understand the mental side, I see that as the only question. He's strong enough to handle the position right now.
