Its true. The college game is really been watered down over the past few years with so many one and dones.
I love Nerlens but, he needs at least another year in college to bulk up. He will get moved around as much as JaJuan Johnson was last year if he doesn't get stronger. But his hand speed and ability to get his hands on balls defensively, his lateral foot movement and ability to guard perimeter bigs will find him a spot on starting NBA teams for a decade.
McAdoo really is the cream of the crop and after that, the sophomores and upper classmen stink and there's only about 4-5 freshmen who would be getting regular playing time within 2 years.
Seriously think the NBA has to reconsider the age limit for incoming players though even with increased age limitations you are just going to have bad years.
