I guess NFL teams dont use your evaluations in making decisions for rosters. He was 4-2 last year and did okay with his stats. The NY Jets signed him to be their starting QB. If he is terrible as your opinion suggests then, he will be benched by midseason and your opinion will be spot on. If he is getting better and lands somewhere between 15-20 rankings at QB then my comments that I think he is getting better will carry some weight. For me their are 4 tiers of QBs Great- above average- average and poor. He will never be great but if he continues to get better, he could move to above average. It seems your only two tiers are good or bad. He is not bad.
