Indianapolis up 2 slots
While much has been made of the play of All-Pro right guard Quenton Nelson (the 'keg stand' TD he scored last week was called back on further review), this upgrade is based on the dominant blocking of center Ryan Kelly. Kelly was part of a monster rushing output of over 260 yards last week against Jacksonville. Kelly had struggled with durability in recent years but the 26-year-old out of Alabama has been a consistent performer all season. The team has a short-week challenge on the road for Thursday Night Football, but the Colts' offensive line should match up well against a Houston defensive front missing J.J. Watt. This line carries a top-3 grade in the latest rankings.
