There's no question cornerback Chris Cook fell out of favor last season under former Vikings coach Leslie Frazier.

Cook irked Frazier when he was ejected from a game against Chicago for making contact with an official. He was beaten in coverage far too often. And there were questions about some of his injuries.

But Frazier is gone. Now, it will be seen if his replacement, Mike Zimmer, is interested in re-signing Cook as a free agent.

"If they want me to come back, I would love to come back," Cook said Thursday in a phone interview. "But ultimately it's not my decision. So I'm just waiting and working out. ... I would be more than happy to come back. I really enjoyed the guys I played with."

Cook said Zimmer taking over could be beneficial to him. Zimmer was an NFL defensive coordinator the previous 14 seasons after having broken into the league as a defensive backs coach.

"From what I've heard, he's probably one of the best DB coaches in the game right now," Cook said. "So that's a positive for me if I get the opportunity to work with him."

One of Zimmer's specialties has been rehabilitating troubled players. Cook has had his share of difficulties since being a second-round draft pick by the Vikings in 2010. He was arrested twice in 2011, on suspicion of brandishing a gun in a fight and for suspicion of domestic battery. He was acquitted in both incidents.
