I've not seen 1 person say that Mitch wasn't bad on Thursday. He was bad, but I would say overall he was more disappointing than bad.
I've made fun of him too. I basically made fun of him the whole time while watching the Texans Saints game, and I posted like 100 times during that game. It just gets to the point of being boring though.
Then there are a bunch of others who are just hating on him. Cutler never got so much hate, not even after one of his magnificent 4 interception performances.
Plenty of people have been trying to deflect blame away from Mitch and onto the OL and Nagy. That is why the hate persists.
Look this is pretty simple. If you are bullish on Trubs, the best you can do is bide your time until he plays well. Trying to defend him, make excuses or look for silver linings right now does nothing aside from feed the trolls.
In short, you gotta know when to hold em, no when to fold him, known when to walk away, know when to run. The hand Trubs dealt his supporters is one where you fold and continue to fold until you get a good hand. Hopefully that hand comes this week against Denver.
