That is heavyweight by G5 standards.
They also had some great TV ratings last year and 2015:
Houston-Oklahoma = 5.7M viewers
Houston-Memphis = 3M
Houston-Navy ('15) = 3M
Houston-Temple ('15) = 2.4M
Houston-Louisville = 2.4M
Houston-Cincinnati = 2.1M
Houston-UConn = 1.4M
Only 2 of those are P5 opponents. Those are true G5 v. G5 heavyweight ratings.
