He didnt imrpove. His arm strength still sucks. He still is a one read qb. He still throws to double and triple covered wrs. He still makes dumb mistakes. He still cant complete a deep pass.
He had the benefit of a top 10 running game and a top 5 defenses that created constant turnovers while having one of the best,if not the best receiver tandems in jets history and he still wasnt good enough.
He is who he is. He did not improve. He put up empty stats beating up on bad teams, we had the easiest schedule in the league for christs sake.
You literally couldnt put a qb in any better position and he still choked.
And you have no alternative...
