Iowa State might be the best 5-4 football team in the country. They've lost 4 games by a total of 11 points. They average 6.9 yards per play on offense and surrender only 5.2 yards per play on defense. For comparison's sake, that +1.7 yards per play differential contrasts tellingly to 6-3 Texas at -0.1. For the record, undefeated LSU is at +2.5.
Collectively, the first effort of the year that resembled some of the lowlights of last year's offense: a second half descent into why-is-everything-is-so-hard grind, way too many 3rd and longs, overall poor play (penalties, Ehlinger's bad INT, bad routes, a couple of OL defeats) in the 3rd quarter, and some struggles with Mountaineer defensive adjustments out of halftime.
If you're feeling pretty confident in the Texas offense (I am) and you think the Texas defense can stop conventional running attacks (probably), then assessing opponent QB play is paramount in reasonably predicting the rest of the season. It's very early with a lot of football yet to be played, but I've got a pretty decent sense of the landscape.
