When OU can run the ball, Gabriel has huge windows to find receivers, and the offense is fluid. When the Sooners can't run the ball, Gabriel's inaccuracy shows, and the offense stalls.
Despite the disastrous offensive performance vs UT, OU's OL may have had it's best run blocking game to date. The OL improved upon that vs a weak Kansas DL. Further growth in the OL will be key to OU's offense. Iowa St, Baylor, and Ok St have average to better DL that'll test OU's OL.
The OU defense has been a tire fire, especially vs the run. The Kansas run game is good, and OU perform okay vs the Jayhawks (with backup QB) rushing attack. That's the only positive. OU's defense just has to try to improve through the rest of the season, again.
I think every game is a toss up for the Sooners with OU holding somewhere between a 40 - 60% pre-game win expectancy. This is very different for OU fans. Just last year, prior to the beginning of the year, OU had a > 70% win expectancy in 9 or 10 games and had a > 50% in all.
