At least get your bullshit straight. He never accomplished it starting in Chicago. He had no problems getting good games, heck, great games with little to no interceptions in Denver.
The problem with Cutler is that he came out of college as raw talent with bad habits.
Well 1 of his" bad habits" was being a loser
In Denver he got rid of those bad habits under Shanahan's coaching, but for whatever reason he reverted back to the bad habits when he played in Chicago. Some would blame it on the terrible O-line that scared him back to bad mechanics, some would blame it on the lack of consistent offensive coaching that could mentor him.
Shanahan screwed himself but starting jay over Jake Plummer in Denver.. Plummer had the respect if the team and was a leader and winner. jay was un-coachable......that's why he reverts back to " bad habits".
Cutler really liked Martz and Gates, and he was improving under both guys, then the Bears let both of those guys go, they also couldn't ever find book end tackles to support the kid. In Denver Cutler played with one of the best Pass Blocking blindside tackles in the NFL - Ryan Clady gave something like 0.5 sacks per year. He comes to Chicago and gets J'Marcus Webb, that hurts, literally.
Either way this happens in the NFL often, guys can be stars in one system and terrible in the next. Steve Young was a nobody before Mike Shanahan brought him to San Fransisco and plugged him into the west coast offense. Systems matter. Football is a team game. The guy came from a strong system run by a good offensive coaching staff with good linemen, he came to a team that didn't have that type of environment.
On Martz, jay got him fired. Same as with Shanahan. In Denver, jay never had a winning record. When jay left Denver, nobody gave a damn.
With jay, it's the same narrative over & over. Here we go: the OL was bad( or was it jay's lack of a quick release), the wr's are bad, the coaches are bad, the system is bad, the "D" is bad, the waterboy is bad, the fans are bad. Everybody is bad except jay. It's always everybody else's fault
Every where he's been coaches get fired cuz their incompatible with jay so-called
"skill set".
Bottom line, jay never had what it took mentally to be a good Qb. He was never committed to improving himself as a Qb.
Ya look at Brady ( this guy with all his success, was just the other day talking about all he's been doing recently to sharpen his skill set), Russ Wilson and even Dak Prescott. All these guys are committed to being the best they can be as Qb's. I never saw jay as having a burning desire to want to be the best. As a 10yr. vet, he was still making the same damn mistakes.
Proof ? Look at his results.
