The Minnesota Vikings, as foreshadowed by head coach Kevin O'Connell after January's playoff loss to the Los Angeles Rams, overhauled the interior of their offensive line this offseason. Center Ryan Kelly and right guard Will Fries were signed in free agency, and first-round pick Donovan Jackson is in line to start immediately at left guard.
The attention on those moves might make it easy to set aside the enviable stability the Vikings have found at both tackle spots. Right tackle Brian O'Neill has started 106 games over the last seven seasons, and left tackle Christian Darrisaw has been among Pro Football Focus' 12 highest-graded offensive tackles in each of the last three seasons.
