Idk they are top 15 in rushing yard lines and top 20 in (not) allowing sacks. They are 3rd in the league in YPC. They are pretty solid from what I've seen. Not sure about elite, but it was an expected strength and so far looks the part through 2 games.
I do NOT believe their RBs are that good on their own. Same as UK. Their OL is absolutely dominating opponents in the run game, far and away #1 in the SEC, I sure as heck don't believe their RBs are really nfl level like stats might suggest.
*Though I do believe Trask continually helps his OL as well. He is quick at decisions.
