Defining defensive success in the Big 12
By Brandon Chatmon
When thinking of Baylor and Oklahoma State, defense is rarely the first thing that comes to mind.
Yet those two teams featured the Big 12’s top defenses in 2013, a main reason they combined for 21 victories and found themselves atop the conference standings heading into the final day of the regular season a year ago.
But neither the Cowboys nor Bears found themselves among the nation’s top 15 defenses in points allowed or yards allowed, and only Oklahoma State's 21.6 points allowed per game, which ranked No. 19 nationally, was among the nation’s top 25 in either category.
Shawn Oakman and Baylor's defense give up yards, but measure up well in the most important statistics.
“I think people are getting educated a little bit about what is good defense and what is good defense against spread offenses when having to defend 18, 19 series a game,” Oklahoma State defensive coordinator Glenn Spencer said. “It’s not yardage, it’s the winning game. Saying you’re the best defense in the nation because you gave up 375 yards per game? That’s ridiculous. That has no bearing on what the best defense in the nation is; that’s the most ridiculous stat ever.”
Recognizing good defense in the Big 12 is a little different.
“How are you going to win the game? How many points per possession?” Spencer asks. “We have a lot more possessions to defend than a lot of teams in the nation.”
So with the new season on the horizon, here are other ways to define good defense in the Big 12.
Yards per play: More important than total yards allowed, yards per play is a better representation for a defense’s success. For example, Oklahoma led the Big 12 in total yards allowed at 305.2, yet the Sooners were sixth in yards per play at 5.38. Why? The Sooners offense played a major role in OU’s strong overall yardage numbers by controlling the clock with its running game. Oklahoma's defense faced 65.1 plays per game, five plays fewer than any other Big 12 team. By comparison, Baylor allowed 4.77 yards per play, which led the conference, while facing 75.8 plays per game. The Bears allowed more yards than the Sooners, but BU’s defense clearly had more success stopping opponents than OU on a play-by-play basis.
Points per possession: Oklahoma State, Oklahoma and Kansas State finished 1-2-3 in points allowed in 2013, but only the Cowboys finished in the top three in points per possession. Oklahoma State led the conference with 1.22 points per possession, followed by Baylor (1.38), TCU (1.5) and Oklahoma (1.6). Those four teams combined to win 36 games, including the Horned Frogs' disappointing four-win season. It’s also a meaningful stat nationally, with Florida State leading the nation in the category (0.9) followed by Michigan State (0.99), Louisville (1.05) and Alabama (1.09). Those four teams combined to go 50-4 in 2013.
Third down conversion defense: Getting off the field on third down is critical in any conference. The conference’s three teams that had double-digit wins finished 1-2-3 in third-down conversion defense. Oklahoma State led the Big 12 at 31.4 percent, followed by Oklahoma (33.7) and Baylor (33.9). Excellence on third down is one reason the Sooners still had one of the Big 12’s top defenses a year ago, even though they faced fewer plays. Oklahoma's offense controlling games wasn’t the only reason the Sooners faced fewer plays, as their defense consistently got off the field on key third downs.
“[In the Big 12] you have to defend the whole full of playmakers and you are going to give up some yardage,” Spencer said. “But you have to get off the field.”
Turnovers: Much like third-down excellence, turnovers are critical in any conference. Oklahoma State (33) and Baylor (28) finished 1-2 in turnovers forced, and it’s not a coincidence. Both defensive coaching staffs make creating turnovers a top priority, even more than stopping the opponent. For the Cowboys and Bears, taking the ball away from the opposing offense is the primary goal.
Percentage of possible yards allowed per drive: This is another terrific stat to monitor the overall success of a Big 12 defense against opponents. BU led the conference at 32.4 percent followed by Oklahoma State (34.7), TCU (35.1) and Oklahoma (37.1). Those four teams could easily be considered the Big 12’s top four defenses in 2013.
Three-and-out percentage: The Bears led the Big 12 by forcing a three-and-out on 28.2 percent of opponent’s drives. Oklahoma State (26.8), TCU (26.7) and Texas (25.8) rounded out the top four. One of the reasons Bryce Petty and the Bears’ offense set scoring records was the ability of Baylor's defense to immediately put the ball back in the hands of the offense.
