The Vikings are one of two 4-0 teams, along with Denver, and one of three undefeated NFL teams, along with 3-0 Philadelphia.

Most impressive to me: They have yet to commit an offensive turnover. Their only turnover so far was Andrew Sendejo's fumble after recovering a Packer fumble.

And: Mike Zimmer's abiilty to take away dynamic receivers. The Vikings have shut down Kelvin Benjamin and Odell Beckham in consecutive games.

That dovetails perfectly with being a strong defensive team.

Concerns: Blair Walsh, offensive line depth.

Positives: McKinnon, who is the subject of my column; Cordarrelle Patterson becoming useful, and of course the defense.
