if manu gets two more championships, is in two more all star games, and raises his scoring average to 20 pts, he'll get into the hall of fame just on his nba career. for the subjective stuff like other championships won, i have no idea.
here are some future hall of famers:
jordan
shaq
karl malone
tim duncan
hakeem
pippen
iverson
kobe
drob
garnett
grant hill
ewing
stockton
webber
kidd
payton
carter
pierce
tim hardaway
mcgrady
steve francis (believe it or not)
marbury (again, believe it or not)
