Your correct, as a GM no one is forcing then to draft.
But with 35+ games vs 95+ games the evaluation process is a lot tougher.
As a athlete I understand.
As a fan I hate it.
You want to make the most money, when your stock is sky high your going to leave, the longer you stay in school the more you get picked apart.
As a fan I have them watch them take some 19/20 year old and wait 5-6 years till they hit their prime in hopes they become something.
They're evaluating them for much longer than 35+ games. Are you familiar with the Nike EYBL league, the LeBron Skills Academy, CP3 camp, Kobe camp and all the other stuff that the TOP prospects go through each year. If it's just a 35 game evaluation, then these GMs and scouts are stealing money. Many of them are anyways, and it's ultimately a crapshoot in a lot of cases anyways.
When y'all say that the rule is better for the league, I hope you mean financially. That's literally the only case. What's the difference between Doug McDermott or Nik Stauskas riding the bench and not being productive in comparison to Mudiay or D'Angelo Russell struggling through their rookie year?
