We have been on the cusp of greatness in the B12. We just needed to get past OU. If OU didn't get Baker Mayfield, we could have 2 more B12 Championship Trophies in the DMC as we speak (2015 & 2017). As it sits, our sole B12 title came in the year Mayfield was forced to sit out.
After Mayfield, lightning struck again in Kyler Murray. But OU is not going to have the Heisman Trophy winner and number #1 overall pick in the NFL every season. Their luck will run out, most likely this year. I'm not sure it mattered who they trotted out against us last year, 2018 was a disaster.
TCU went 0-5 against Mayfield (I'm including the TTU loss). There's zero shame in that, Baker did that to a lot of teams. Today it feels like OU is unbeatable, but that's because they've beaten us 3 times in 2 years with a MOV > 3 TDs.
But before Mayfield, in 2012, 2013 (when we were really bad), & 2014, we were 1-2 against OU. Our 2 loses came by 3 and 7 points.
In 2015, we lost by 1 point after Baker dropped 2 TDs and Seibert got 3 FG's (all for >35 yards) to get 23 points for OU in the first half. Baker didn't play the 2nd half and Trevor Knight couldn't move the ball on us. TCU outscored them 22-7. Their sole second half TD came from a busted play - a 72 yard TD run by Perine. Foster Sawyer started that game and got a majority of the snaps. BK came in down by 17 with 2 mins left in the 3rd and we were a failed 2 point conversion away from winning.
