We were discussing this over in Conference MEGA thread already...
The B1G folks think this is "brilliant" because it provides (to them) a much needed conference expansion relief off ramp. Their "empire" is arguably in the weakest position (too many members no one cares about and institutions who will never care either) long term from a strategic standpoint--especially national footprint and demographic trend patterns. The SEC, ACC, and to a degree Big 12 (the PAC-whatever is a basket case) occupy that high ground for the forseeable future. Say what you will about SEC bottom feeders (perhaps save Vandy), but those fanbases and institutions will bankrupt and die trying to become relevant. Obvioulsy ACC and Big 12 are hybrids og B1G and SEC in terms of commitment...and that probably shakes out if still travelling conference expansion road. That's why its strategically inconceivable (never underestimate muppets however) B1G would pass on Miami if conference expansion continues, but for no other reason than SEC containment/encirclement.
BUT...if they [B1G] can get "everyone" to go along with SuperTournament To The Rescue! concept...that goes a long way in giving lifelines to ACC and maneuver space + time to Big 12 (Yormark has a big reputation afterall). B1G would basically be outsourcing conference expansion without having to bring in new members and pay that bill/dilution (nothing is for free long term)...thereby not having to face tough decisions of jettisoning their weak herd members in 2030s or during a SuperConference merger.
At face value, why wouldn't ACC and Big 12 be all-in on this? Buys time and space...
Also, don't even get started how useless and meaningless the bowl games are...not even scrimmage value at this point it seems...so from a roster standpoint (and perhaps unseen hand of NFL), showcases talent just a touch extra...I get thats a stretch..but still...
Careful what you ask for B1G, you just might get it.
