TCU went 2-2 on 4th down attempts on Thursday, so that sounds like a positive....well, sometimes it’s the sins of omission that are just as evil as the sins of commission. TCU had two more opportunities where it could’ve attempted a 4th down conversions, times when it was not necessary, but perhaps an optimal choice. Early in the 2nd quarter, TCU had a first down at the Texas Tech 33 yard line; an overthrow to Savion in the endzone, a JoJo Earle run and an Emani Bailey run set up 4th & 2 from the 25.
