IMO with the right coaching there is no reason that the linemen that we have can't get the job done. We don't have world beaters like Orlando Pace, but they are good enough to get the job done if properly coached. There are 3 factors that go into playing offensive line: feet, strength, and brains. For OSU you would hope that the linemen that they recruit have all 3, and I think most do. I personally made it through my career solely on brains and was able to manage.
I don't watch the line very much especially when I'm at the game like this past week, but here's some things that I noticed. Our linemen never cut block. If you want to successfully run zone blocking schemes you HAVE to cut block to slow down backside pursuit and open up the cutback lanes. If you watch a Broncos game at least 1 lineman cuts someone one every single running play. The cut is also good for the outside guys on screens and quick passes to get the DL's hands down.
I also noticed that it seems like the line isn't working together on the zone double teams. In order to drive the DL off the ball the linemen doing it need to pretend that the are connected at the hip. To me it looks like the D-linemen are able to get between the linemen before they are able to get together on the double team. Athletically there is no reason for this to happen. Good coaching should correct these technique problems.
To tell the truth without watching some film I don't know what is wrong with the pass protection, but the line didn't give Zwick much time on Saturday. I think the linemen are better pass protectors than run blockers, but the pass protections that we use need some work. On the other hand fans need to realize that Wiscy might have the best DL in CFB so that is going to make any line look worse than they are. The line should be good enough to provide the QB with 3 seconds on normal dropback passes. There are probably things the coaches could do to shore everything up.
The biggest problem is scheme and play calling. A coach needs to see what his guys are capable of doing and play to that. Sometimes I see glimpses of what this offense can do when the defense is on their heals and don't know what is coming at them and it is a beautiful thing. Most of the time it looks like the defense knows exactly what is going to happen every play. I would like to see some type of misdirection happening on every play. Send players in motion more often. Run a couple reverses a game, and fake the reverse on every other normal running play. If a safety, and OLB think that you are handing the ball to Ginn on an end around they aren't going to be able to stuff the inside run. I wish JT would watch the film of what teams like Cinci, Marshall, and NU were able to do to us and steal what worked well.
