Neither, for now.
I want to see how CUSA, SBC, and AAC perform over the next 1-2 years. I do not believe the AAC & SBC are much better, especially after we lose the 6 members to the AAC which include a lot of dead weight.
CUSA will have superior basketball, in my opinion, assuming MT continues to play well. CUSA could become one of the strongest non-Power 5 basketball leagues if MT were able to get back to it's ways.
With regards to football, I believe the league will be much stronger than most realize. NMSU will always be a bottom feeder in football, that's fair and a given considering they've made 1 bowl game in like 20 years or something crazy. But WKU is still a solid program, Liberty is a f'in Juggernaut, SHSU could be the next App St., and Jacksonville State will be a big wild card. La. Tech is La. Tech and will always be at minimum a respectable Football and Men's B-Ball program and could surprise us all this year on the gridiron. Ruston fans might be unpleasant but they typically have solid to great teams. UTEP has finally returned to respectability on the gridiron and hardwood and should be able to at least be a formidable opponent in OOC play. When I look at CUSA I don't see any real bottom feeders that lack commitment and always suck (ie. the FIU's and Rice's of the world). NMSU is awful in football but they have a GREAT basketball program. I don't think people realize how good NMSU basketball is, they would have been #1 in attendance in CUSA if they were in the league last year. Very well supported program that consistently makes and wins in the NCAA tournament.
I actually think a lot of CUSA's success, or failure, will hinge on a program like MT. Will MT go back to sucking in basketball and 4 win seasons in football? Or will MT get back to 20+ win seasons on the regular in basketball and push for conference championships in football? The other big factor is, will Liberty and others stick around or jump ship the second they taste success and get the offer to "move up" ? If everyone stays put and makes a commitment to build this league and MT does it's part, we would actually be in a great position to be better leagues than both the AAC, SBC, MAC, etc.
I actually like the new CUSA, and I'm excited to see how things play out. Sure, SBC/AAC is getting some good programs from us, but they're getting some bad ones too. And UAB is due to lose their coach/regress, and same goes for UTSA. Marshall's coach is a dud and will lose them plenty of games, and App St.'s luck hitting on all these recruits I do not believe will continue. Same goes for Coastal. It's very likely that many of these flavor of the month SBC programs that have experienced success come back down to earth and regress.
CUSA has a big opportunity here to kick some tail, invest in it's programs, and re-brand itself. I wish we had a better front office because I don't have any faith in Judy, but if the conference wins and wins big then her incompetence will hopefully be overshadowed. We must get back on ESPN networks. The CBS/Facebook/BEin experiment was a failure. Acknowledge it and move on and be better.
As for MT, it is time to get serious about your major athletics programs. Dirt should have been moved a decade ago but it wasn't. Now you will spend 2x or more for the same upgrades, but that's your own fault. People have been asking and talking about the needed upgrades for 15+ years. Gonna have to bite the bullet and go all in here or just shut it all down. No point in being a pretender. McPhee gonna have to get that checkbook out and if we have any big money donors left they are too.
