Yes, the one and done is an NBA policy, nothing the NCAA can directly do about that. There is also no question that the G-League (or any minor league) wouldn’t have nearly the glamour and therefore value that the NCAA does. The NCAA is what it is because of how it’s intertwined with schools and March Madness, bowl games, etc… It’s the perfect marriage really.
You’re also correct with the stipend, this was changed about three years ago if I remember correctly. As for getting ‘paid’, the idea behind this stipend was that the scholarship covered tuition and room and board, but didn’t cover other living expenses that one might incur (Ex. transportation). And since it’s unrealistic that these athletes have a job, it did make some sense why it was added. I’d caution saying they get ‘paid’ though. While I’m sure they get more than enough to cover expenses, these checks are meant to cover their room and board, books, transportation, etc… To be clear, I don’t think an additional stipend from the NCAA would fix any of what we have going on right now because the NCAA could never provide the type of money a guy like Deandre Ayton will get from bag men.
For most athletes these scholarships are more than appropriate compensation. But I think where this topic was going was that some athletes (elite ones) bring in considerable value that the NCAA has long exploited. The courts said as much in the Ed O’Bannon case where they ruled the NCAA violated anti-trust laws. It was either that case or one similar that led to the cost of attendance stipend. Because some athletes bring such great value, teams have turned to cheating (paying players) in order to give them the best opportunity to win. Ed Martin and Michigan getting caught didn’t stop anyone, and while the well might dry up for a couple years, I won’t be surprised if it starts flowing again once everything blows over. The NCAA has zero investigative power to stop it (and I’m not so sure they even care to stop it), so you can be sure there will be coaches willing to take that chance in order to receive fame and millions of dollars as a high profile coach.
