Now, your saying the whole family should pick up and move with the kid? Or have the mom leave the rest of their family? It is different for international student coming for college because many believe the United States offers the best level of education. Same for young European prospects playing in the NBA. Don't get me wrong, if a high schooler in the U.S. grows up wanting to play professionally in Europe, he has that right to go pro out of high school. Why doesn't he get that right for the NBA?
How did it go from "someone" to the whole family. It doesn't have to be mom. It could be an older brother or a trusted friend of the family. Not every student attending college in the U.S. does so because they come from an underdeveloped country with a lesser education system. Whether they do or not doesn't change the aspect of homesickness that you brought up, so it isn't different. He doesn't get that right for the NBA because it's not a right, it's a privilege. The NBA is the employer. Why is that so difficult to understand. The NBA is to the european leagues is equal to what Google is to syracuse.com. What qualifies you to work for one, doesn't qualify you to work for the other, and just like google gets to determine it's criteria, so does the NBA. They own the right, not the prospect.
Europe has had its own struggles with players not getting paid and things like that. Regardless of what you may think (if they aren't able to get living expenses paid for) it is a substantial investment by the family to send him to Europe for a season with the only reason being so he can wait his year for the NBA.
The lower level european leagues have trouble paying players, not the upper level leagues that someone of NN's stature would play for. Did anyone ever hear of Ricky Rubio not getting paid?
What is the proof that the NBA product was watered down? Doesn't the advent of the NBDL help to eliminate that? Doesn't getting more players quality coaching help the overall NBA product?
If you watched the NBA a few years ago, it was obvious. If it wasn't obvious, you don't know the sport. The NBDL doesn't eliminate it because the NBA doesn't invest in it enough to be a MLB level minor league system, and they don't have to if they don't want to. Right now, college coaches and the level of competition in college are superior to the NBDL, and, therefore, college is a better developing/weeding out ground. If you want to argue this, tell me how many NBDL coaches coached for the U.S. international teams the last 8 years.
While the employer has that right, the NBA is the only sports league that doesn't allow prospects with the ability to contribute to be drafted after high school.
Because it's not in their best interest to pay millions to these prospects to develop/weed them out, if they don't have to. It's no different than any large corporation.
