Nothing will fix Trubisky, no matter how much you want them to fix him. Better O Line going to fix his piss poor mechanics, or teach him how to read a defense? When you have a ton of X players bashing him and pretty much calling him a bust.....guess what, he is a bust. Those X players know a hell of a lot more than we do.IMO, the Bears have little choice other than to list Trubisky as their QB for next year. How about they spend big and grab Winston? That's the kind of choice they have if they don't use Trubisky. Draft a QB in the 2nd, pay for a questionable veteran or use Trubisky.
I'm as disappointed in him as you guys are but there isn't an easy answer. Maybe, if the Bears use free agency and the draft to fix the O line, he might do better? I think the O line was more of a problem than Trubisky was.
Notice they haven't commented on picking up his 5th year option yet. IIRC, they have until May to decide. I'd bet they're looking for alternatives. Hopefully they have some kind of plan.
The best answer I can think of is signing some good O coordinator who also can evaluate draft talent. He takes over play calling from Nagy and convinces Pace that players X,Y and Z will fix the line. They do and Trubisky settles down with time to throw. Will this happen? Probably not but it's a better answer than dumping a QB who would be instantly signed by another team. IF Trubisky bombs next year, the Bears have a first round pick in 2021 and could make a move then. Next year is make or break for Trubisky and, maybe, Nagy and Pace.
