According to this article, Mavericks owner Mark Cuban says the D-League is a better option for an 18 year old than playing in college for one year and leaving would be.
I think he might be right. Seriously, if you’re only going to college because the NBA age rule says you can’t go to the NBA out of high school, then why not go somewhere and get professional coaching, and some cash, and let some kid who actually wants to go to college use that athletic scholarship?
I don’t get the age limits for pro sports at all. Maybe that’s just me.
