The Marc Trestman era in Chicago lasted just two seasons, with the second full of turmoil.
Bears tight end Martellus Bennett told NFL Network's NFL AM on Friday morning that the coach struggled to control a locker room full of personalities.
"Trestman, I think, first off, the issue that he had, probably, was managing us all, all the different personalities," Bennett said. "There's a lot of big personalities (in the locker room). And I think, for a first-time head coach in the NFL, dealing with all the personalities that you have, I think that's hard when you got guys like me, you know, (Brandon) Marshall ... Lance Briggs on defense, (Charles) Tillman.
"There's so many guys with such outgoing personalities that managing those guys and bringing them all together is what a leader needs to do, you know? And that's one of the toughest things."
Trestman recently signed as the Baltimore Ravens' offensive coordinator, a job that Bennett said fits the former coach better.
"Calling plays, he was excellent," Bennett said. "I think he's going to be an excellent coordinator for the Ravens. Strategically, he was great. But on the field, guys just weren't executing.
"A lot of it comes back to the player preparation. If you're not preparing to a high level, then the coaches can only do so much; the game's not played on paper, it's played on grass. On paper, we look great. On grass, we looked bad."
Trestman will attempt to top Joe Flacco's best season in Baltimore, while Bennett and Jay Cutler try to turn things around in Chicago under John Fox and Adam Gase.
On paper the swaps look great. We'll see if they work out on grass in 2015.
