As for best team ever .... it may well be these Warriors.
Jordan is the best player ever, but that doesn't mean a team couldn't be constructed that's better than the Bulls. An All-Star team is better than the Bulls, I mean the Warriors are pretty freaking close to at least an All-Star starting 5 and then have an above average bench to go with it.
That's not really a knock on the Bulls, it's just more of what an unusual circumstance the Warriors are.
The Warriors are akin to basically taking the 95-96 Bulls and adding Patrick Ewing or David Robinson to them on top of what they already had.
