The second bad call the officials made on Arkansas was the targeting penalty on Kansas's 2 pt play in the 2nd overtime.
There was clearly helmet to helmet contact but that's doesn't make it targeting. First, the Kansas QB was not defenseless because he was running the ball. Second, by rule targeting on a runner can only happen if a defender uses the crown of the helmet on a tackle/hit. Pause the video below at 0:04 and you can see the Arkansas player hits the Kansas QB with the side of his helmet, not the crown. This should have been overturned.
