Imho, Cam is not a good leader and he may be an awful one. Only time will tell, but he has only shown me reasons he is a poor leader to date and no reasons to believe he will ever be a good one.
Cam does have a good deep ball, I just think RG3's is better.
You'll never see me argue Cam's athleticism and strength, but it takes more to being a great QB than athleticism and strength. Upstairs, I don't think Cam has it in him to ever be great. Record setting and fantasy asset? Oh yeah, but that doesn't win titles. I think RG3's head + skills stand a much stronger chance of winning titles than Cam's head + skills. RG3's head >>>>> Cam's, Cam's skills >> RG3's. At any other position other than QB a good argument could be made for Cam, but QB is too reliant on a guy's head and I don't trust Cam's. There's no reason not to trust RG3's.
And, no, I'm not one of those guys who says all of this stuff off of scouting reports, internet, and one bowl game. I've followed RG3 his entire time at school and watched 8 of his games (TCU, K State, Texas A&M, Ok St, Iowa St, Oklahoma, Texas, Washington) in full this year. Dude's legit.
