Let's look at some games:
2012 OU: Offense generated 362 Yards, and scored 17 points. The key to that game was TOP-34 mins, and 3rd down conversions: 50%
2012 TCU: Offense generated 260 yards of offense, and scored 23 points. Really an anemic effort, game won on defense.
2012 Baylor: Offense generated 362 total yards and 24 points. A horrible 286 yards passing on 51 attempts, only 5.6 yard per completion and an even worse 2.5 yards per rush. Terrible offensive performance.
2012 Oregon: 282 yards of offense and 17 points. 132 Net Yards Rushing . . . again, a complete disjointed and inept overall offensive performance.
