The defense alone will be good enough to win more than 4 games but this offense has been figured out. They need to be less RPO centered, Brock can run that in his sleep but sometimes he's too robotic and teams are figuring out how to influence his choices, which results in them dictating what we do on offense. Texas showed teams how to play Brock last season and basically every team since has defended him similar to what they did. We need to be more proactive and put pressure on defenses rather than letting them decide what we will do. That may not mean chucking the ball deep, it may be getting guys like Milton and Jones involved in the running game, Kene or Lang getting touches in the passing game etc....
Not finishing drives, but 7.7 yards per play against a good Iowa defense is outstanding. Two games is a small sample size. While points being out of whack in either direction to yards per play can suggest a real problem in style or execution, it can also be something that's a bit flukish that normalizes as the season goes on.
