Our offensive line is clearly not where we need them to be -- which is to be expected after replacing three NFL linemen. Right now our offense is largely one dimensional. Smoke and Co. are putting up ok stats but are clearly not a real rushing threat.
When C Rod returns, his running (and blocking) ability should allow us to be more well-rounded. Those runs that have been going for 3 yards will suddenly go for 6, which will be a huge difference. Also, he's a warhorse who exhausts defenses. Smoke has proven to be a mediocre player here. At his best, he can come in against a tired, bruised defense and gash some big runs. He's basically an upper-middle class AJ Rose.
Without a run game, we can't control the clock like we are used to (which could have bitten us against Florida). That puts too much pressure on Levis to try to create big plays with his arm, leading to too many sacks and interceptions. With our defense, the ability to go on those time killing Bataan Death Drives that suck up clock after we get a lead will be absolutely devastating. I worry that the defense has been on the field too much thus far. We've got much better depth than we did in years past, but our regulars are so outstanding that I don't want to see us lose anyone because they have to take too many snaps.
I don't think C Rod's return is a magic elixir to fix the o-line but I do think he's such a good rusher that he will instantly make the offense better by taking pressure off the line and Levis to have to make everything happen through the air. Or, to quote Mark Stoops, "See everyone appreciates the run game now. Five years ago they didn't appreciate shit."
