I think the Bears horrible offensive line holds Jay back quite a bit and I think he has a better upside than Smith due to his ability to make throws that Smith can't . As far as his personality
Upside?
If anything Cutler has shown zero progression over his time in the league, you can check em out by the year, he plateaud in his first year, his rookie season was his best. If anything Alex is actually improving and Jay is the same old Jay.

Besides the him having a big arm (not quite accurate of one though) what does this guy have over Smith?
A big arm is just that, a fukking arm. Kyle Boeller had an arm too
