It really doesn't matter what the situation was, the fact of the matter is Ben played his first year, much ahead of schedule, and not only survived, but thrived. One can argue that Pickett is even touted as being more "NFL Ready" than Ben was in his rookie season.
Sure it was a better overall team in 2004, but it's not like this squad is an absolutely terrible one (comparing this team to most teams that start a first round QB).
I would not be so much in favor of him starting if Trubisky has shown himself to be competent and not a total waste of time, but he has been. Until he shows me something, my opinion will not change. I have to say my patience for him has never been that high considering I've watched a lot of Bears games over the years (3 good friends of mine are bears fans and we often get together to watch games), and this year's Mitch looks like the same one in 2019 (not good)
