"I know what kind of coach Dean Pees is. I look at the season and the improvements that we made — especially in the back end — throughout the course of the season, and that's what you look for," Harbaugh said. "… We still have plenty of work to do, but I trust Dean. I know he is a very good coach. All those guys — I know they are good coaches. You work side by side with a bunch of guys through a season like this, you find out what they're made of. And I like our guys."
