Option 1, they remove the California teams from the NCAA. The Power 5 have been talking about a "division 0" league for a long time. Chances are that would push them all to leave the NCAA and create their own organization.
Option 2, allow California to be the exception. This would be great for California, because if you're a top high school athlete, would you rather play in California where you could potentially make millions, or anywhere else? Presumably a bunch of other states would pass similar laws and demand the same exception, until the NCAA was forced to allow paid players everywhere.
Or Option 3, just change the NCAA rules to match California, and let players get paid.
If sounds like the only winning move here is for the NCAA to allow paying players. I think California just forced their hand.
