15. Minnesota Vikings: Strengthen the defense
The Minnesota Vikings have a very underrated offense. Kirk Cousins proved last season that he is capable of getting wins in the playoffs and he is surrounded by some great talent. Wideouts Justin Jefferson and Adam Thielen are one of the best duos in football and Dalvin Cook is a top-2 running back in the NFL.
Mike Zimmer runs a tight ship in Minneapolis and the expectation for the Vikings is almost always playoffs or bust. This past season was very disappointing as the defense really let them down in big spots. If the Vikings can protect Cousins and add playmakers to their defense, we may see a much different team in Minnesota next year.
