Well, the Top 44 is alot better than the Top 64 which is what the P5 is today. Moving into 3 tiers of 44, while allowing from some movement between tiers, would lead to significantly more money for most of those in the P5 today. The bottom of the P5 would (e.g. Vanderbilt, Rutgers) get relegated but they would be in the minority.
For the Super League being proposed in soccer, those 12-15 clubs are going to dictate the terms from the rest of soccer. The upper crust of the P5 could, and likely will, do the same.
If there is more money to be made, the elite schools will find a way to make it.
