You can't blame TCU if it doesn't get excited about this matchup. The Horned Frogs are off a huge 29-22 home win against then 15th-ranked Oklahoma State last Saturday. This is their only nonconference matchup of the season. 
Louisiana Tech is the much fresher team. The Bulldogs have played just once since November and that was last Friday when they defeated North Texas. 42-31, on the road. 
The Bulldogs can score averaging just under 32 points per game. They are 27-11 ATS the past 38 times as a road 'dog.
TCU has not shined as home chalk going 5-21 ATS the last 26 times as a home favorite.
