Offensive efficiency sparks Baylor, K-State and Oklahoma

They've done it in very different ways but Baylor, Oklahoma and Kansas State have been the Big 12's most efficient offenses during the past three seasons. The Wildcats do it with efficient playmaking, the Sooners have leaned on the running game and the Bears used explosive speed and big plays. All three teams have won 20 games and lost seven games in the Big 12 during the past three seasons.

Here's a look at the Big 12's points-per-drive rankings since TCU and West Virginia joined the Big 12 in 2012 (conference games only).

1. Baylor 2.96

Conference record: 20-7

Summary: The Bears have scored 1,213 points, 44.9 points per game, during this three-year span. Bryce Petty earned Big 12 offensive player of the year honors in 2013 as he passed for 4,200 yards, 32 touchdowns and three interceptions while leading the Bears to their first Big 12 title.

Key stat: The Bears have also led the Big 12 in yards per play with 6.65 since 2012.

2. Kansas State 2.71

Conference record: 20-7

Summary: A pair of exceptional quarterbacks, Collin Klein and Jake Waters, have joined Tyler Lockett to give the Wildcats one of the top offenses in the conference. Lockett had 231 receptions for 3,464 yards and 26 touchdowns as the Big 12’s top playmaking threat during the past three seasons.

Key stat: The Wildcats averaged 9.18 yards per pass attempt, best in the Big 12.

3. Oklahoma 2.51

Conference record: 20-7

Summary: This offseason has made it easy to forget the Sooners had one of the Big 12’s top offenses in recent years. Thanks to Damien Williams, Brennan Clay and Samaje Perine, OU has rushed for 6,158 yards as the Sooners leaned on their running game, particularly during the past two seasons. Williams, Clay and Perine each recorded at least 1,000 rushing yards during the span.

Key stat: The Sooners have averaged a Big 12-best 5.54 yards per carry.

4. Texas Tech 2.13

Conference record: 10-17

Summary: The Red Raiders have passed for 9,834 yards (364.22 passing yards per game) since 2012. Davis Webb, Seth Doege, Baker Mayfield and Patrick Mahomes have had their time behind center for Tech during this span yet the Red Raiders' passing attack remained productive regardless of who ran the offense. Tech’s 64 turnovers and minus-30 turnover margin have kept it from seeing that offensive production transform into Big 12 title contention.

Key stat: Tech’s 63.5 completion percentage is the Big 12’s best.

5 (tie). Oklahoma State 2.07

Conference record: 16-11

Summary: The Cowboys offense has taken a step backward after being among the Big 12’s best units before 2012. Clint Chelf, Joseph Randle and Josh Stewart were among the Cowboys' key contributors during this three-year span but the explosiveness that became commonplace in Boone Pickens Stadium definitely disappeared at times, particularly in 2014.

Key stat: OSU’s 83.1 goal-to-go touchdown percentage was second in the Big 12 behind OU.

5 (tie). West Virginia 2.07

Conference record: 11-16

Summary: Outstanding receivers helped the Mountaineers remain productive with Kevin White, Tavon Austin, Stedman Bailey and Mario Alford creating problems for defenses. WVU would likely be even higher on this list if Dana Holgorsen’s team capitalized on red zone opportunities. WVU converted 58.3 percent of its red zone possessions into touchdowns, ranking eighth in the Big 12.

Key stat: WVU averaged 4.44 yards per carry (third in the Big 12) during this span, bringing balance to the Mountaineer attack.

7. TCU 1.98

Conference record: 14-13

Summary: TCU’s offense was turnover-ridden during the Horned Frogs first two seasons in the Big 12 before Trevone Boykin sparked an offensive explosion in 2014. Boykin, the 2014 Big 12 offensive player of the year, has been one of the conference’s top playmakers as a passer, runner and receiver but 62 turnovers have served as a anchor to the offense.

Key stat: The Horned Frogs got 62.7 percent of their yardage through the air, ranking third in the Big 12 and higher than Baylor and Oklahoma State.

8. Texas 1.97

Conference record: 17-10

Summary: UT’s quarterback struggles are well-documented and have hampered the Longhorns’ offense. Their 1.2-to-1 touchdown to interception ratio was ninth in the Big 12. There was talent on the 40 acres but the offense never really seemed to find a rhythm or transfer that talent into consistent playmaking.

Key stat: The Longhorns were pretty solid on third down despite their struggles to score, finishing fourth in the Big 12 by converting 42 percent of their third-down attempts.

9. Iowa State 1.56

Conference record: 5-22

Summary: ISU’s offense hasn’t excelled in the running game or the passing game during this span as the Cyclones averaged 5.9 yards per pass attempt and 3.84 yards per carry. Injuries and struggles along the offensive line have hurt but ISU must improve drastically if it hopes to return to a bowl game.

Key stat: The Cyclones offense won’t make a drastic jump on this list without doing better at limiting negative plays. ISU had 38 percent of its plays end up with zero yards or negative yardage, worst in the Big 12.

10. Kansas 1.06

Conference record: 2-25

Summary: David Beaty is tasked with jump-starting this lackluster attack. KU ranked last in most categories. James Sims, who rushed for 1,751 yards and 12 touchdowns, was the main bright spot during this span.

Key stat: The Jayhawks' 4.49 yards per play was, by far, the worst in the Big 12. ISU was second at 4.88 ypp.
