2 changes the NCAA can make are allow undrafted kids to retain their eligibility and allow kids to make money off their likeness.
The second is on the way. The devil is in the details.
The first is more problematical because it potentially puts coaches in a situation where they sign enough guys in April to fill up their roster and then don't have the scholarships for potential returnees in June.
And I think this under-estimates the passion these guys have to play for pay. I strongly suspect most undrafted players will prefer the G-League or overseas route over coming back.
It would be way cool if the NBA would allow players to go pro after high school but also require them to stay in college for two years should they elect to go to college.
This would really help the college game. But what incentive do the NBA and the Union have to go along with this? Not sure I see one.
Look, I grew up in an era when Oscar Robertson, Jerry West, Jerry Lucas, Lew Alcindor, Bill Walton, David Thompson and so many others stayed in college through their senior seasons. In other words, the talent-level equivalents of Zion Williamson, Anthony Davis, Kevin Durant, et. al. played college ball as seniors.
So, the slide has been going on a long time and I don't see anything that can stem that decline.
