Kid, it's not a perfect solution, or system.
But what they have now, overall, isn't working.
That's my point. You're right Williams did stay 4 years.
But there are more Leon Smiths lately than ever before.
If you make the age minimum, it might wind up making sense to some of these kids to go to class. What would they have to lose if they went to class? If the NBA wouldn't take them until 21-22, then they might as well.
The league needs a few new ideas. Bit saying mine is perfect, but they need to do something.
