ESPN NBA

I believe that high school players should be able to make the jump directly to the NBA if they so please, but I would be in favor of an "at least two years in college" rule if a player chose to enroll in school. However, because the NBA's most recent collective bargaining agreement allows for college players to enter the NBA draft after one season, freshmen are in great demand at draft time.

But not all one-and-dones are created equal. In this year's draft, three of the first five players drafted were freshmen: John Wall, Derrick Favors and DeMarcus Cousins. All are expected to make an immediate impact. But others, like Texas' Avery Bradley and Kentucky's Eric Bledsoe and Daniel Orton, were taken in the second half of the first round and come with much more risk of being draft busts.

Here are my top 10 incoming freshmen to keep an eye on with regard to next June's NBA draft, a list that I will periodically update as the season progresses. I am not advocating that all of these players enter the draft, but the reality is most of these 10 will.

1. Harrison Barnes, 6-foot-8, North Carolina Tar Heels
It will be an upset if Barnes is not one of the country's top players this season and the top "one-and-done" guy in next June's draft. He is a prototype small forward, an athlete with myriad offensive skills and a championship caliber attitude to match.
