10 games that defined the Big 12 in 2015

The Big 12 had a lengthy list of games that defined 2015.

Big plays were made, memories created and the conference's first-ever playoff participant earned its way into the national title hunt after a shocking setback.

Here are the top 10 games in the Big 12 this season:

1. TCU 55, Texas Tech 52: Aaron Green’s improbable game-winning catch off a tipped pass will be one of the lasting memories of the 2015 Big 12 season. The teams combined for 1,357 yards of offense and 14 offensive touchdowns as two of the Big 12’s best offenses went toe-to-toe.

2. Oklahoma 44, Baylor 34: One of the most physical and competitive games of the entire season saw the Bears suffer their first loss ever at McLane Stadium. Baker Mayfield’s scramble and touchdown pass to Dimitri Flowers was a defining moment in Oklahoma’s Big 12 title run.

3. TCU 52, Kansas State 45: The greatness of Trevone Boykin was on full display against K-State as TCU’s star quarterback helped his team rally from a 35-17 halftime deficit. He was at his best in the final quarter, going 5 of 6 for 87 yards and one touchdown while adding five carries for 106 yards and two scores on the ground.

4. Oklahoma 31, Tennessee 24: The Sooners' overtime win in SEC country was the first sign Bob Stoops team could have playoff pedigree. Its stars rose to the forefront when it mattered with Mayfield, Zack Sanchez and Sterling Shepard making critical big plays in a rowdy road atmosphere.

5. Oklahoma 30, TCU 29: With an ailing Boykin sidelined, TCU rolled into Norman and was one two-point conversion away from an upset of the Big 12 champions. Steven Parker saved OU’s national title hopes with an instinctive pass breakup in the final minute after TCU outscored the Sooners 22-7 in the second half.

6. TCU 28, Baylor 21: The Revivalry was something to behold. A torrential downpour turned this game into a battle of wills and field position before Boykin scored a touchdown on the ground and found KaVontae Turpin for the game-winning points in double overtime. It was ugly but memorable.

7. Kansas State 38, Iowa State 35: The Wildcats trailed 35-28 with 1:30 left in the game before chaos ensued. Two Iowa State fumbles turned into 10 points and an unbelievable Kansas State win that kept alive the Wildcats' hope of another bowl appearance.

8 Oklahoma State 70, Texas Tech 53: This Cowboys road win is representative of the journey Mike Gundy’s team took to a 10-2 record. A fourth quarter which featured six combined touchdowns and 475 combined yards solidified Oklahoma State’s place in the Big 12 title race as the creative Cowboys offense outscored Kliff Kingsbury's team.

9 Texas 24, Oklahoma 17: The Big 12’s most talked-about outcome of the season left Charlie Strong in the Golden Hat, searing the image of his first victory in the Red River Showdown into everyone’s memories forever. The wake up call sparked Oklahoma’s run to a playoff spot and underscored the inconsistency and potential of Strong’s bunch.

10 Texas Tech 35, Arkansas 24: Few people expected the Red Raiders to march into Fayetteville and leave with a win. But Kingsbury’s team showed it was much improved after a disappointing 2014 and the third year coach enjoyed the win, taking a shot at Razorbacks coach Bret Bielema during his postgame comments.
