Would be surprised if OU is ranked at the end of the season.
At this moment their RB's (which is usually a strength for them), WR's and DL are not special; not bad, just not anything special. Their top two rushers from last year are gone. Four of their top five WR's from last year are no longer with the team. Their top three sack producers from last year are gone.
They have a transfer QB (Gabriel from UCF) starting, a head coach in his first year as a head coach and their most tenured coach was fired a little over a month ago for repeating a racial slur.
They are headed out the door of the Big XII so they probably won't receive favorable 50/50 calls.
I don't see how OU holds it together this year.
