What makes you say the coordinators deserve the credit for their success instead of Jim? No beef, honest question
The DC (who is black) managed to coach up a nice secondary and had an opportunistic defense this year, but overall wasn't given the tools he needed. No pass rush this year. I wouldn't say he propped Caldwell up recently.
On the flip side Caldwell actively harmed the offense for four years. First OC was a historic disaster. Second was better but implemented a simple baby offense due to Caldwell. No focus on run game. In fact Caldwell outright stated he didn't need to focus on the run game.
Caldwell is similar to Fisher in the sense that he's a dinosaur of the past who refuses to change with the times. It's time to move on or we'll win 7-9 games yearly thanks to weak schedules. BTW if Caldwell stayed I wouldn't be stunned if we won 10 next year because teams that miss the playoffs get a weaker strength of schedule. And then the next year we'd win like 8 games, miss the playoffs, and be in the same position again. No more.
