The Minnesota Vikings will not use their franchise tag on Case Keenum according to Ian Rapoport of NFL Network. This news doesn't really come as a surprise to me especially with the heavy speculation that they're going after Kirk Cousins. Case Keenum, is not worth the salary that would be attached with the franchise tag. Sure he had a fantastic year, however so did Ryan Fitzpatrick a couple seasons ago, and how did that turn out. The Vikings are smart in the front office and know Keenum greatly exceeded expectations last season. They aren't going let the success of last year blind them into spending a ton of their cap space bringing him back, when they know damn well he can't win them a Super Bowl.
This confirms that the Vikings will be looking elsewhere for QB options this offseason. With that being said Case Keenum still very well could end up on the Vikings, just at a much lower price than they franchise tag. If they have to bring back Keenum it shows that they have little to no faith in Bridgewater coming back and being their future QB. It also means that Kirk Cousins ended up going elsewhere. This is definitely good news for Vikings fans to hear because when it's announced they signed Keenum back they'll realized they're right back to where they always are. A good team with a very mediocre quarterback.
