As a Bears fan that hangs on every play, this guy's assessment is bang on. The Bears are a 5-1 team that is currently 3-3 and could have had a chance to beat the Pats if not for 2 special teams TDs. The most important point here as well is that zero out of the three Bears losses are Trubisky's fault. They lost to the Packers because of Nagy and because Kyle Fuller can't catch. The D gave away the Miami game (5th most yards allowed in franchise history) and the Pats beat us on special teams. Trubisky's play is not costing the Bears games.
He is also sailing wide open receivers at an alarming rate. But again, here is the most important point, he IS improving. Week 1 against GB, the narrative was that Mitch was accurate but had no pocket poise, panicked when he felt the rush, and couldn't make a read outside of the primary. Then against NE, it was "He makes good reads and shows poise in the pocket, but can't throw accurately" And, at the time they were said, neither were wrong. Taken together, we have a QB who has all the tools and just needs to bring it all together. And I think he will, it's just going to take some time.
I think I posted it before, but I'll say it again. For one reason or another, people love bashing certain players and Trubisky is one of them, likely because the Bears traded up to get him (which was viewed as stupid) and because Mahomes is a prodigy. The most recent other example is Goff, who was a joke for the first two years of his career. The two situations are strikingly similar to me, and I think that once Mitch figures it all out, he will be an above average QB, and perhaps well above average, similar to Goff.
Mahomes is better than Trubisky, I will admit the obvious. But that doesn't mean that Mitch is bad or that the Bears are dumb. Teams miss on picks all the time, including the immortal Belichick. But they don't have a whiff on their hands. Trubisky is clearly very talented, and has the tools to become very good. Given time, he will reach that potential. And in the meantime, he's already a QB1 for fantasy without any reason to think that it will change.
