The Vikings put forth considerable effort last offseason in boosting their offensive line.
Minnesota signed tackles Riley Reiff and Mike Remmers early in free agency and traded up to make sure they drafted center Pat Elflein in the third round.
In addition to bringing in those three players, Minnesota also shifted some of what it wanted offensive linemen to be able to accomplish.
Pat Shurmur added a few more outside zone run plays, and Minnesota incorporated more screens into the passing game in 2017.
Shurmur has departed to become head coach of the New York Giants, and he has been replaced by Offensive Coordinator John DeFelippo.
