Trestman's redemption

"We've all been battered around, gotten kicked in the teeth and gone through challenges," Carroll said. "He is a good example of a guy who fought through it and came out the other end of it in a great spot."

He is a good example of a coach who can go into the halftime locker room of what appears to be a hopeless game, experience an epiphany, tear up the game plan, and then charge out to beat the world.

Trestman was on a fast track to be an NFL head coach at an early age. But he never was ready for this moment until this moment.

It took each of his 57 years to make this NFL head coach.
