Martellus Bennett: Marc Trestman will be an 'excellent' OC for Ravens

Chicago Bears tight end Martellus Bennett offered some insight Friday into what went wrong during Marc Trestman's two-year stint as head coach.

"Trestman, I think, first off, the issue that he had, probably, was managing us all, all the different personalities," Bennett said during an appearance on NFL Network's "NFL AM."

"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."

Bennett also gave Trestman a vote of confidence in his new endeavour as offensive coordinator of the Baltimore Ravens - a job he thinks is better suited to his former head coach.

"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."
