This is a "NO BRAINER" folks, you have to go with Mr. "Separation By Preparation" Russell Wilson.
Newton (like Vick) is skittish, and has a tendency to run far too often.
There's a damned good reason that these two have not become the super stars that the prognosticators hype would have us believe.
Yes, Wilson is playing for a far better team than Cam, but here's a couple of the differences that spells success for Wilson and not for Newton
1. Wilson adapted to the alterations cerebrally, and used that foundation as a launching pad, started tying his skillset to the new demands, and worked his ass off with the others in the offense to make it work
He hasn't forsaken or forgotten all that he's learned for Years now, but rather, tied the new in with the old.
With Newton, what you've seen, is what you'll likely see going forward, or, unless his coaches (who have relied solely on his athleticism) dishes up a new fare for him, and his ability to make the mental changes.
2. Wilson is just far better at speed reading Defenses, and after watching game film on them, and preparing for those particular confrontations, he can make adjustments for them a lot quicker.
Not taking anything away from Cam Newton's God given athleticism at all, but I'd bet a month's pay, that Wilson has the upper hand cerebrally, and that he is constantly working on the mental aspect of his position.
12 wins in one year vs. 14 in two?, like I said in the beginning, "This Is A No Brainer"
Hell, I'd even put KaePrick ahead of Newton at this juncture.
