In my opinion, it was the best draft class ever. It included most notably Michael Jordan, Hakeem Olajuwon, Charles Barkley, and John Stockton. Those four players combined for 7 MVP awards, 23 All-NBA first-team selections, and 45 All-Star game appearances. Some other notables in the draft were Otis Thorpe, Kevin Willis, Michael Cage, Sam Perkins, and Alvin Robertson. The 3rd (Michael Jordan, arguably G.O.A.T.) and 1st (Hakeem Olajuwon, top 5 center of all time) picks combined for 8 championships alone (MJ 6, Hakeem 2).
Even some talk about the missed pick of Michael Jordan, where with the No. 2 pick the Portland TrailBlazers took Sam Bowie who averaged 11 points and 8 rebounds in his 10+ year career. The No. 5 pick, Charles Barkley, became one of four players ever to record 20 thousand points, 10 thousand rebounds, and 4 thousand assists. John Stockton (drafted 16th by the Jazz) later became the all-time assists leader and one of the top 5 greatest point guards in League history. The draft class compiled 12 championships among all of them.
But the most amazing part of this whole draft class is that the 1984 draft included 2 of only 4 players ever to record a quadruple-double in a game (Hakeem Olajuwon and Alvin Robertson). This, to me, seems like the best draft class ever, bar none.
