I mean, they SHOULD be better. Return all 5 starters, add 2 the should contend to start from the portal, get Hasert back from injury plus RSFR available to play. Not to mention 2nd year of the new OL coach and 2nd year of the new S&C staff. If they aren't at least above average this year, I don't know if it's possible here.
I still contend that scheme plays a bigger part than OL talent or technique. When you play with a fullback, it's pretty easy to see where the ball is going and when you're going to run it. I love Stevo Klotz and the guys who played the position before him. But, it isn't a surprise (to me) that our best OL play of the Campbell era was when Soehner was playing F. He was a legit threat in the passing game, could seal the edge AND lead block. Even though we had no deep threats, the offense wasn't predictable because Soehner was versatile enough to catch a pass or attach to the line and seal the DE. Seems like now, if Klotz is in, you know we are running and all you have to do is fly to wherever he is and you're likely going to get a TFL. Pretty tough for an OL to succeed when the defense knows exactly what you are going to do.
