I disagree with the "marketable" part as right now the upperclassmen are cashing in, that will die down in time. Essentially you will have big donors paying high school kids to go to their school. Whether kids play or perform is secondary, all of the "big" name kids leaving high school entering the NCAA world will cash in on their national signing day when they sign on to play at a school.
And after each season (in every sport) free agency begins, and you will have great players at all schools fielding offers from "businesses" (aka donors) telling them I got $20,000 for ya to be a "brand ambassador" for my company if you transfer to (insert school name) and play for them.
Now a lot of this stuff was happening already many will say and sure it probably was. But now with everything above board it's just going to cause this to explode. The "have's" will be the land of riches and dreams. and the "have nots" are just a farm team to feed the bigger name schools once said player reaches a certain level.
And just wait till Nike, Addidas, and Under Armour get involved and start directing kids to schools they have deals with. Oregon and Maryland might see an uptick in the talent they are able to land.
