1. Minnesota Vikings
The best defense in the league a year ago somehow got better in the offseason. DT Sheldon Richardson adds another pass rusher on the interior. His presence will make it difficult for offensive lines to slide their protection to Everson Griffen and Danielle Hunter on the edges. Linebackers Anthony Barr and Eric Kendricks will offer more pressure on Mike Zimmer’s famed double-A gap blitzes. Harrison Smith might be the best all-around safety in football, and the Vikings replaced Andrew Sendejo with George Iloka, giving them one of the league’s deeper safety groups, The cornerback group is just as deep after the team drafted Mike Hughes in the first round. He’s been excellent during preseason and could push Trae Waynes for playing time across from Pro Bowler Xavier Rhodes.
