2. Cam Newton
Cam Newton clearly cannot be a starting NFL quarterback any longer in this league. The toll that the hits have taken has changed his ability as a passer and not for the better. However, in Arthur Smith's offense if you can play he will find a way to use your skill set on offense. If the Falcons were to part ways with Heinicke why not try to bring in Cam as a wildcat quarterback or short-yardage weapon.
The team could put Logan Woodside as the primary backup with Newton serving as a short yardage and special package weapon. The biggest question mark in this scenario is whether or not Cam would be willing to return in such a role and for his former division rival no less.
3. Jake Fromm
The former Georgia Bulldog is a very limited backup but in Arthur Smith's system could be decent depth. Fromm is one of the few names still in free agency that is unlikely to get a chance this season barring trade or injury. Despite a strong preseason the struggles he had in the league and limited upside clearly make this a move only if you believe in Woodside and Ridder.
