Things that have yet to happen, in my opinion:
1. Big 12 implosion - will it happen before 2024 (would need multiple departures to circumvent GOR clause)? I think we can all agree that the long term outlook (post 2024) for the Big 12 is on life support. ESPN manipulated them big time and 7/8 current members will find themselves in the desperate "UConn Club" once the Big 12 falls apart. Personally, I don't think Texas will leave until it absolutely, positively has to (read: OU leads a mass exodus out). By default, that cements the Texas faction to the conference and should provide some measure of stability until the GOR expires.
2. Notre Dame has to pick a side - Independence or ACC? There is zero incentive for ND to join the ACC from a financial standpoint. They get full share of ACCN money PLUS full share of their own NBC money. If UConn had a similar sweetheart deal handed to them by the ACC, I wouldn't want to give up independence either. But as long as the CFB Playoff remains at 4 entrants, the odds of a 2-loss ND team, with 12 games, getting into the Playoff field are not good. The *ONLY* reason for Notre Dame to join the ACC is to get a shot at playing that coveted, meaningful 13th game and, thus, improve their Playoff resume. What I think will happen is that the Playoff field will be expanded to 8 and that will buy ND a few more years to make a decision.
3. Monopolizing the NCAA Basketball Tournament. Yes, yes...there is too much "history" and warm fuzzy feelings surrounding those feel-good Cinderella stories (F George Mason), but at some point, the Power schools are going to take a good, hard look into how they can make more money from basketball. Why? Youth football participation rates are at record lows. The NFL is incredibly behind the times in enacting player safety rules and concussion effects are a very, real and scary consequence of playing a game. At some point, sports fans won't have the same blood-thirsty love of football. Whether it comes from the long overdue player safety rules being enacted or from the declining numbers of kids playing football in favor of other sports, who knows. Basketball is America's second favorite sport, for the most part, and the Tournament is always must-see TV. Right now, the NCAA owns it and, as a result, controls the cash flow. But that can and will come to an end. For the same reasons why power schools began monopolizing football money, they will want to monopolize basketball money. Big schools with big fanbases don't want to share money with small schools - which is what most of the G5 and mid-major basketball conferences, like the Big East, consist of. This likely won't happen for a while but it will happen.
