First, I believe Carr is just putting his name out there and he will be back.
That said, I think we are going to start seeing more and more basketball players leave early/forgo college. There are a number of opportunities throughout the world for players to play against similar and sometimes better competition, make money, avoid the NCAA's nonsense, and retain their draft stock.
I think you saw it with Amir last year. Leaving early often is not all about going to the NBA. That's the end goal, but there are a number of different roads that lead to that destination now. I keep seeing people say things like X amount of players entered the draft and only Y were actually drafted. There are false assumptions in that analysis that (1) players will improve their stock if they return to school; (2) their journey ends at not being drafted; and (3) the players didn't fully understand that was a possibility.
Going forward, there will continue to be a growing number of players who leave/skip school to play professionally. This will range from likely lottery picks (LaMelo) to fringe prospects. It's a viable alternative.
For those of you worried about some of these guys getting degrees, I think we will have to agree to disagree. Many of these people will a substantial amount of money playing internationally/two-way NBA contract/etc. They'll likely make more money from the ages of 18-30 than the overwhelming vast majority of people who graduate from Carlson. They can save money and return to school later.
