That's a bad model IMO. Thanks for the link btw --your comments didn't have enough context until I read it. I would echo a couple things:
Not having a team is going to affect player development. Colleges may not be for everyone, but you get to choose a coach you like and trust, and they have a ton of incentive to develop you the best they can. Even if you hate academics, North Carolina will make sure you get the grades
G league play seems like a free for all in comparison to college.
I'm really speculating here, but the money seems uncompetitive if they've only picked up 5 guys. Having read so many scandals and rumors, and contracts guys have signed abroad, that seems like low-balling guys who are chasing money or pride for having signed professionally, especially if you consider tax vs under the table benefits. And looking at opportunity cost for those who aren't looking to cash-in, college seems pretty safe vs G league. Colleges have a ton of staff for all aspects of development, great medical staff, trainers, etc., and the atmosphere can't be beat. You can also get professional insurance, if you're in that elite group of potential lottery picks.
Yeah, the G league is trying to improve, but this looks like a smaller step than they made it out to be. Makes me think the owners haven't committed to the idea of a farm system, or see the long term value of it growing the brand.
