No reason to blame Frost for the offensive staff being complete failures this season, which is on Rhule.
If Rhule doesn't have high level assistants, that's on him. If he hasn't figured out NIL, that's on him, and if he can't in game coach at this point after holding 3 head coaching jobs totalling over a decade of time, that's on him.
Ty Rob is coming back because of the culture and I suspect that they will fare pretty well in keeping contributors out of the portal because of the culture. Rhule's flipped it. It ain't broken so now let's not shovel more shit on the worst coach of all time and look to Turd to hold his $90 million man accountable
