We didn't have a good NBA draft in years. The last one was back in 2003 when you had Lebron, Carmelo, Bosh, Wade, and David West being drafted. Four out of the five was in 2008 Olympics.
Also you have a few who are having a decent NBA career now, Kirk Hinrich, Diaw, Outlaw, Perkins, and Barbosa.
But in this year's draft you are not going to have players like that drafted. Instead of having 5 or powerhouses being drafted in this year's draft, we are going to see 5 players from the same school (Kentucky) being drafted.
