I think we are starting to see the effects of NIL. It will be very hard to keep a dynasty together. The biggest losers may end up being the top notch programs. I don't mean you can't keep together a high level playoff caliber team, that's still possible. But having these super teams that just club every opponent to death may become rare. The new norm may be that even top teams lose 1 or 2 games per year.
For years kids would much rather wait their turn to start on Georgia, or Clemson, or Ohio State, etc. Not anymore. Now if a kid isn't getting significant playing time by sophomore year, they're gone. How many kids are going to pass up cash in hand plus playing time? Not many.
The real key to having a top program is depth. It gets you through injuries in season and it lets you not miss a beat when kids go to the NFL. Now it will be much harder to have quality depth.
That's why Bama and Georgia are struggling. They are used to having a highly ranked junior to step in and start for the guy who just went to the NFL:. Lots of those guys left for other programs, so now they are passing the torch to freshmen and sophomores. That means mistakes.
This also means that lower tier teams will be more dangerous. You may see a lower tier team that has tons of 4th and 5th year seniors starting and now they're dangerous simply because they make few mistakes and they can take down a top team that has a bunch of inexperienced new starters. You see that all the time in the NCAA BBall tournament. Some blue blood program gets taken out by a 12 seed that has 5 seniors starting plus 3 more seniors off the bench.
The is why the Big 10 and SEC are working together to try to guarantee that they get more teams in the playoff. They are seeing the writing on the wall that a 3 loss SEC or Big 10 team will likely be better than a 1 loss Big 12 or ACC, or lower tier team, and they will have played a much tougher conference schedule.
