Those three classes are set in stone. In fourth place, however, is the still-very-active class of 2003. The '03 group includes four likely Hall of Famers: LeBron James, Carmelo Anthony, Chris Bosh, and Dwyane Wade. And considering James looks like he has 15 to 20 years of peak-level play ahead of him*, the 2003 class could still climb higher up the list. They accomplished this despite the notable handicap of Darko Milicic and his paltry 7.1 win shares at No. 2.
