I wouldn't touch the Cam Newton comp for a few reasons:if his comp is Newton (hopefully) newton had a crap ton of INT's his first year but had a lot of rushing TDs, i honestly think Fields could legit be a RB in the league
1 - Usage - When Cam went to Carolina they were a run heavy offense where he essentially became their goaline back. No way Nagy sings that far in his scheme.
2 - Body - Newton had over 20 lbs on Fields at the same point in their careers (entering the league).
3 - You don't want that - Cam just turned 31 and he's somewhat of a shell of his former self. So many hits and injuries. If you think about it he's aged more like a RB than a QB, which is not what you want. IMHO you want Fields running, but also showing he knows how to avoid contact. If that's the case he shouldn't be fighting for that last yard to cross the goaline.
