I largely agree with you. We expect a better run game.
The odd thing about this is that the Buckeyes ran for 5.2 yards per carry and passed for 7.5 yards per attempt.
The rushing would have been good for 16th in the country last year.
The passing would have been good for 58th in the country last year.
Even though that makes it look like the Buckeyes ran better than they passed (and with Trey, I think they did), I think the most untapped potential so far is in the run game. Sure, the pass game looks like an easy fix with just a couple of drops early; and Ryan said there were some things that WH will see better when he's had a few more reps in the system. But once the OL gets their feet under them, and I think they will, I think the run game is this team's fast ball.
