Hope it works out for him. In spite of his size I really think he could make a solid NFL QB if given a chance. I mean he always outperformed the other teams QB (Bridgewater) for example. So his size never hurt him before and I say he will gain some weight and end up a jewel in the rough.
I didn't even think he'd get that. Glad he did though. Hopefully he proves everyone wrong. He will 100% have to add weight though. No way he'll survive, even if he does get a contract, if he stays around 180.
