I think CUSA is just that bad this year. The conference RPI is around 20th right now. The top team is Middle Tennessee at 77. Eight teams are in the 200s or 300s. It's bad.
It is bad but Marshall is also better. I remember going into that game expecting a train wreck but came away actually impressed. Their talent is young so it will take time, and I don't know if D'Antoni will be able to recruit, but his system seems solid. If he gets some shooters in there they could be dangerous.
