Houston Baptist was one of the teams that played last week. That's an advantage for the Huskies because Texas Tech has yet to see action. 
The Red Raiders have a very good QB in Alan Bowman. But he hasn't seen action in a year due to a broken collarbone. The Red Raiders are breaking in two new offensive tackles so they want to be careful that Bowman doesn't get hurt again. If Texas Tech jumps to a big early lead it would be risky and foolish to keep Bowman on the field. 
Houston Baptist isn't going to hold Texas Tech in check. But the Huskies can produce points behind a high-volume, spread offense that their offensive coordinator, Zach Kittley, learned during his time as an assistant coach at Texas Tech under Kliff Kingsburgy. The Red Raiders had one of the worst pass defenses last season.
