Earlier, we touched on the Big 12's Red Zone Touchdowns Allowed Percentage.
Now, let's look at the Big 12's best and worst at scoring touchdowns once they got the ball into the red zone.
Red Zone Touchdown Percentage
1) Texas — 44 red zone touchdowns scored, 63 offensive red zone attempts, 69.8 percent
2) West Virginia — 41-59, 69.5 percent
3) Oklahoma — 46-67, 68.7 percent
4) Oklahoma State — 48-72, 66.7 percent
5) Texas Tech — 45-68, 66.2 percent
6) Iowa State — 27-41, 65.9 percent
7) Baylor — 45-69, 65.2 percent
8) Kansas State — 45-71, 63.4 percent
9) TCU — 28-57, 49.1 percent
10) Kansas — 18-39, 46.2 percent
Surprised? Texas had the Big 12's top short-yardage back in Joe Bergeron (if you don't count Kansas State quarterback Collin Klein), and the Longhorns' overall ball-control attack lent well to continued use in the red zone. One wouldn't think that a spread attack like West Virginia could be effective in that role, except that the Mountaineers had Stedman Bailey, an absolutely exceptional route-runner who created space even when there wasn't much room to operate. Bailey had 25 touchdowns by himself, and while they didn't all come in the red zone, a number of them did. Oklahoma, of course, had the Belldozer.
The bottom end of the spectrum were marked by teams that couldn't get out of their own way. Kansas State had three potential drives killed by "other", meaning they likely ran out of time, as the Wildcats did in the first half against Kansas. Add those three drives in, and the Wildcats are a top-half team in the league at 67.6 percent. TCU had the most turnovers in the Big 12 with five fumbles and three interceptions in the red zone. And the Jayhawks were largely undone by no passing game (a league low five passing touchdowns in the red zone) and five drives that ended on downs, the second most in the Big 12. Give Kansas four more passing touchdowns (to match Kansas State, the league's second-worst team in the category), and have the Jayhawks score on those five times they were stopped on downs, and they're among the top teams in the league.
In the red zone, the margin of error is just that thin.
