MOBILE, Ala. -- The Minnesota Vikings have one hire to make to fill out their coaching staff for the 2015 season, but it appears the rest of the group is intact for the long haul.

Coach Mike Zimmer said the Vikings plan to extend the contracts of most of their assistant coaches through the 2016 season and will promote coaching assistant Drew Petzing to take over for former assistant receivers coach Klint Kubiak, who left for a job at the University of Kansas. The Vikings have one coach who wanted a one-year contract, Zimmer said. But as many teams do, the Vikings will roll over their coaches' contracts before they're working into the final year of their deal.

When asked on Tuesday about the length of his own contract, Zimmer said it runs past 2016. The Vikings have not announced the details of Zimmer's contract, but what the coach said on Wednesday means, at the very least, he has a four-year deal (or possibly the same kind of three-years-with-an-option contract given to his predecessor, Leslie Frazier). Given the progress the Vikings made in their first season under Zimmer and the optimism surrounding quarterback Teddy Bridgewater, the team could be putting together a foundation that will stand up for years to come.
