I wouldn't view zone blocking schemes as a bandaid. Several of the best offensive minds in the game (Shanahan in SF most notably) employ the system because of how effective it is at moving the attack and creating opportunities for play action. I don't know who is to blame for why the team can't identify linemen, but it's a problem. That's why I pushed back on the idea that the Vikings haven't drafted guys that have started for them - they have (Elflein and Samia to name the two most recent) - the problem is they aren't very good. But neither are their high picks like Bradbury. The team is struggling to coach and develop or identify guys who they can coach and develop. I don't know the diagnosis, but the team's with the best OLs in the league aren't burying every first round pick into their line. They're the Packers who take guys in rounds 2-7 and keep manufacturing bad asses. Philly did the same on their run. Dallas tried and most of those guys are washed up or gone. New Orleans has done well, but they also have developed a lot of 2/3 round guys to where they are. That's the path to a better OL - better identification and development for their scheme. But, make no mistake, good OL play is in a drought that is seriously harming the product on the field right now. Virtually every team in the league, including pretty much all of last year's playoff field, have OL as a need. Personally, I trade back, grab the best pass rusher, and then bury my next two picks in the best guys on the OL I can find. There will be good talents that are long term starters in the NFL in this draft taken later.
