Cam Newton will be good until his natural athleticism starts to wane; when that happens, he'll fall off. I think it's obvious he doesn't put in the time to be an all time great. I think it's funny when beat writers say they'd chose him over Luck, RGIII, Kaep, and Wilson. All of those guys are excellent above the shoulders. Cam is probably the most gifted from the shoulders down. That works for every position on the field other than QB.
I pretty much agree with this.
In fact I don't think much of Cam as a QB at all.
He has tons of physical gifts, speed, athleticism and the like. Pretty much everything you would need in every position OTHER than QB.
I still stand by my earlier prediction, that within 5 years he will have been benched, traded or cut.
