So I've been critical of the interior OL, and I still am, but I think they need a coaching change. I don't know anything about (checking....) Chris Kuper but I think a lot of the issues is on him because these guys do not look prepared for situational blocking.
Obviously the QB and OL are never going to pick up every blitz pre-snap, but why is it that every delayed blitz up the middle gets through? Why don't the guards or center ever shift off the guy they are blocking to slow down the guy running freely with momentum? You could see it yesterday, they were looking at the blitzer but chose to stick with the lineman they were already engaged with, even though that defender didn't have momentum building towards the QB.
Additionally, our screen passes to the backs seem to never work, and at least yesterday I saw why. The Vikings had four OL out in space to block three defenders. However, none of them engaged until Aaron Jones was already wrapped up. They BEAT the defenders out there. Maybe they were all taught to be mindful of PI and not engage early, but they were not in position nor ready for the catch. Not a single one of the lineman were positioned between Jones and the defenders, and it didn't look like they had a plan for whom each of them should block.
