Leslie Frazier has been busy the past two weeks trying to fill various jobs on his coaching staff. Now, it looks as if he could have an unexpected opening.

The Buccaneers are believed to have made an offer to defensive line coach Karl Dunbar to coach the same unit in Tampa Bay and there is little the Vikings could do if Dunbar decides to accept. Unlike many of the Vikings assistants, his contract is expiring and he will become a free agent. If nothing else, this will create some nice negotiating leverage for Dunbar.

Dunbar has been the Vikings defensive line coach since 2006, when Brad Childress hired him to be a part of his first staff.

The Buccaneers' defensive line has been coached by Todd Wash but his contract is set to expire as well. Last season was Wash's first working with the entire defensive line. He had been the defensive ends coach in 2009.
