Only need 1 guy with $100M+ net worth for a basketball team worth of salary. He would be the "owner" for all intents and purposes, just with no revenue for his "business".
I'm not saying it's impossible, I just don't think it's going to be common or the typical model. I'm not worried about a random non traditional power program here or there with one giant booster supporting a traditional non-power team. I don't think there are going to be 20-50 of those. In football it would be even less likely to see that as the common model, maybe if we had this 30 years ago Oregon does the same thing they did with Nike except this time it all goes directly to the players. I just don't think you're going to see some massive shift in who the traditional powers are in both sports, rather just the "haves" will have more.
I think more common will be teams that have the brand, have the tradition, have the fanatical fan base, and have the boosters pulling even further into a new realm. Certainly some were probably already doing that with some cheating in terms of recruiting. Some places have always had an edge in recruiting without cheating, I live near UCLA now and it would be an easy sell just with the various scenery/weather before even getting to the historic winning.
These are my "thoughts" and they might be wrong (who among us really knows where it's going even day to day). Apologies to those who don't think this board is for people discussing their thoughts.
