luck is a much better athlete and runner than most gave him credit for (goes along with being a white athlete...for some reason you are assumed to be just smart but slow and not very athletic. stereotypes suck.).
that said, luck has nothing on newton as a runner. he'll still be a great QB and likely the best one taken in the draft this year.
I agree. He is a good runner. Very tough when he runs. But his runs are in the mold of The Golden Calf of Bristol, not Newton or Vick. Newton, as I said, has freakish change of direction for someone that is 6'6, 250-260lbs. That is what makes him so difficult to stop in open field. I still remember that LSU run for 2010 where he just made one of the top defenses in the nation look silly. Luck isn't capable of something like that. He relies more on sheer power (his thighs are pretty big) than he does making you miss in the open field.
Griffin is a talented runner, but I don't think he has the COD or agility that Newton/Vick have to really take over a game with his legs like Newton and Vick are capable of if they wanted to.
Heck, he wasn't even that
good of a runner in college. He finished the season averaging 3.9 YPC - that is pretty bad, and Griffin was in an even more wide open offense than Cam was. Newton averaged 5.6 YPC in college (against the SEC) and 5.4 last year IIRC. Even led the SEC in rushing yards and TDs too. This isn't directed at anybody but I just don't see how anybody could really expect Griffin to make an impact on the ground like Newton did. When you watch them play, you can tell Newton is superior with his legs and it isn't really close.
