I'll slap you with my member
So quick cursory research on the posted all decade teams by way of win shares per 48.
'10 sample size is too small
'60 that stat doesn't exist
'70 that stat only goes through half the decade (and I don't recognize half of them. I know.)
So that leaves only '80, '90, and '00
'90 is 1.0575. Intersetingly if you sub David Robinson(.2502) for Dream(.1767), it jumps to 1.1513 and with that sub not one player would be under.2053 (Malone).
'80 is .7822 but it is missing Isiah as this stat is not available for him. But even if it were higher than MJ's who has the highest at .2505, the '80 team wouldn't catch the '90 team.
'00 is .8366 but again a players number is missing (Iverson ). But again his would have to be as high as MJ's for the '00 team to catch the '90 team.
There you have it. Of the three, according to win shares per 48 it is the '90 team and it ain't even close.
And the best team in the 90s won 6 titles (6-0 i'll add) and it was all done by 1 guy.
FYI
