I would go with the 2003 draft. That is the one with Bosh, James, Melo and Wade right? I am only fourteen so I don't know too much about the draft years before I was born. That is the best one that I have seen.
I definitly think it would have to be 1996:
Allen Iverson, Marcus Camby, Shareef Abdur Rahim, Stephon Marbury, Ray Allen, Antoine Walker, Kobe Bryant, Peja Stojakavic, Steve Nash, Jermaine O'neal, Zydrunas llgauskus..and thats just the first round...
I like the old school 1960 draft (back when only 7 or 8 people were drafted at a time): Oscar Robertson followed by Jerry West.
I really like the 1999 draft:
Elton Brand, Steve Francis, Baron Davis, Wally Szerbiak, Richard Hamilton, Andre Miller, Shawn Marion, Jason Terry, Corey Maggette, Ron Artest, James Posey, Andrei Kirilenko.
A lot of our future superstars have come in the 2003 draft:
Lebron James, Carmelo Anthony, Chris Bosh, Dwayne Wade, Chris Kaman, Kirk Hinrich, TJ Ford, Luke Ridnour, David West (Hes getting good), Boris Diaw, Josh Howard (what a steal at pick 29!)
You have to put up here 1984 only because of the four players:
Hakeem Olajawon, Michael Jorgan, Charles Barkley, John Stockton
'84 '96 and '03 are top three no doubt, but don't forget about '85. Patrick Ewing, Karl Malone, Charles Oakley, Joe Dumars, Chris Mullin, Arvydas Sabonis, Spud Webb, Manute Bol are all household names, and pretty good players too.
1984: Come on, it had Jordan!! However, for me it was also the worst EVER!! Thats when my Blazers picked Sam Bowie over Jordan. I still imagine sometimes a team of Porter, Jordan, Drexler, Kersey and the Duck and what might have been. <sigh>
