Contracts, pay scales, more organized professional type model is coming. I would expect some sort of collective bargaining coming as well.
It makes zero sense for colleges to just willy nilly give kids money without expectations of getting something in return. It makes zero sense for the turnover to be what it is. It's just people moving around for no other reason than they can. A lot aren't getting paid what they think they will, and they're not even getting the playing time/role they think they're signing up for.
Right now, everything is kind of new so there is no standard practice. That will change with time as kinks naturally get worked out. An organized market, free agency, pay scale, rules, transparency, etc is coming.
It's in the best interest of the programs and conferences. Maybe even pros, especially basketball.
NBA has declined in ratings, a large part of that is they don't have an incubator of stars. Which college could, should be and was for the longest time until the age rule/OAD. NBA screwed themselves and college game with that.
CBB hasn't had a star or stars in years. There are no good rivalries anymore. Kids just aren't sticking around long enough to cultivate those things. The elite talent is bouncing after a year, and there's too much turnover with everyone else who isn't going pro.
I think the big execs and decision makers are starting to realize this. When conferences realign and finish evolving into whatever they're going to be, and all the media/tv/money rights are figured out folks are going to see that it's in the best interest of all that some order and stability be maintained.
