Here are Tee Martin's USC offense ranks against FBS teams with winning records, take it for what you will. I like to do it this way since it gives somewhat of a quality team versus cupcake teams.

Yards/Game: 422.7 (37th)
Yards/Play: 5.98 (34th)
Off Points/Game: 23.7 (67th)

Martin had no problem moving the ball his first two years, but he also had the benefit of a Sam Darnold/Ronald Jones/JuJu core in 2016 and Darnold/Jones/Burnett core in 2017. I think the alarming stat here is the inability to convert RZ opportunities into TDs, which he's never been good at during any part of his juncture. In my opinion, this is where you really find the true quality of an OC's play-calling aptitude. The ability to get it across the plane when the defense is on high alert and has a much smaller ground to cover. We've seen it time again since the Golden years up until Richt, where we get a bunch of chunk yardage, only to have to settle for 3 points instead of 7. The elite offenses of the world like the Clemsons and Oklahomas are hovering at 65%.
Some will say Tee gets a pass in 2018 because Darnold/Jones are gone. But those numbers above are absolutely horrible, given it was year 3 of his offense.
If he ends up coming here, he's going to need to bring in or develop elite talent at the QB position or else it's most likely will end up being Richt/Rosier pt II
