Andrew Raym may prove to be too good to redshirt, although Creed Humphrey was redshirted in 2017 and he's a top pro prospect. I expect Raym to be starting at center in 2021. If he plays this year, he could see action at guard or center.
OU has the bodies in the OL with lots of highly recruited players. It's just a matter of who steps up the most in Bedenbaugh's eyes.
Right now, I'm waiting to see if there will even be a 2020 season. If the 2020 season gets cancelled, OU would be bring in the equivalent of two good freshmen classes in 2021 as Riley would certainly redshirt the entire 2020 class.
