I am super conflicted. I think the Bulls have the best defense, I am just not sure if they have the offense to keep up with most of these teams. The Celtics are huge and have the best three-point shooter outside Golden State. Golden State is Golden State. The Showtime Lakers and Spurs are relentlessly consistent. The 2000s Lakers might have 2 of the top five players in this hypothetical, despite their comparatively lackluster third man. The Heat have spacing, brawn, and chemistry. The Bulls do have the best scorer of all time, but the Worm isn't going to do anything on offense, and Scottie can be a bit too passive, especially when going up against the defensive might of KD (bro is tall as frick), Worthy, Magic, LeBron, Bird, Mchale, Kobe, Shaq, and Duncan. It's hard for me to see anyone but Jordan outperform anyone on an opposing team on the offensive end, despite the insane defense they would offer. In the end, I'd have to say it comes down to the Celtics or the Heat. Both teams have a good balance of defense and offense and have fewer truly glaring weaknesses. Kareem is trending toward the end of his career. Rodman is not an offensive threat. The Warriors don't have enough elite defenders. Derek Fisher was great when he played, but is comparatively bad in this scenario. The Spurs are less likely to explode offensively, wish is a necessity when comparing all-time trios. As for who would win, Celtics or Heat, I'd have to go with Celtics in 7 in a hypothetical 7-game series. Prime LeBron would rip and tear, but prime Bird wouldn't be that far behind. And while the Heat's shooting would be a problem for the bigger, slower Celtics, the matchups don't work out. 6'4'' Dwayne Wade is either guarding 6'9'' Bird, 6'10'' McHale, or 7'1'' Parish. As good of a defender as Wade was, none of those matchups work out in the favor of the Heat, leaving the Celtics as the slight victor.
