Having been out here for the 2014 season, I'm not sure this statement is entirely accurate.
OU was rebuilding that year, but still put up some significant numbers offensively. Unfortunately, they just had better teams out there and the defense was not doing them any favors either... but it certainly helps when your brother is head coach.
Anyway, both he and Jay Norvell were co-OCs and fired in the same year making way for a young, brilliant OC to come in. The thing is, had OU had a semi-decent defense (and they didn't until Mike Stoops got fired) they possibly could have flipped a few of those games that year. The points were there for at least three wins but when you're not playing defense, it practically comes down to whomever had the ball last.
If anyone is to blame for the 2014 season, it really was Bog Game Bob and his brother.
