Mike Priefer has been special teams coach for the Vikings since 2011. In all those years, he has coached fundamentally sound special teams units. He’s been instrumental in drafting kickers twice - Blair Walsh and Daniel Carlson - and has had to scramble later to replace them. He’s had Marcus Sherels as punt returner nearly his whole tenure, and Cordarrelle Patterson among others as kick returner. He’s gone through a few punters as well - including 5th round draft bust Jeff Locke, Chris Kluwe, Ryan Quigley, and now has Matt Wile.
