TCU is no offensive firecracker at full strength. Now, owing to injuries, it must lean on two recent third-stringers, QB Grayson Muehlstein and RB Emari Demercado, as starters. No scholarship players back up Demercado. Hence, Okie State can ring up points below its norm and still maintain room for error. The Cowboys opened the season with two games in the 50s. Since, they’ve reached the 40s six times and the 30s twice.
