People done forgot how good Jordan and that Bulls team was.
The question comes down to defense. The Bulls were one of the best defensive teams of all time, with three of the best individual defensive players of all time in Jordan, Pippen, and Rodman. Lebron would be guarded by Pippen and while he may still get 25-30, it'd be the hardest 25 he's ever going to get. Kyrie is guarded by the bigger Ron Harper, who was no slouch on D, and has to work for his points, especially as Jordan and Rodman would likely float to help prevent penetration by Kyrie and Lebron. Jordan would guard Smith, who isn't going off in that scenario. Rodman would give Kevin Love all he could handle when the Cavs are on O and pull in double digit rebounds without breaking a sweat.
When the Cavs are on D, who's guarding Jordan? Smith? Please. If they want to make it as tough on Jordan as possible, they're putting Lebron on him. But that leads to a Cavs loss in 5 in my mind, because Lebron would have to devote so much energy to slow Jordan that the massive offense they'd need from him would be curtailed big time. And even then, no defender in league history is stopping Jordan from getting 30 in the playoffs. Who's guarding Pippen? If Lebron is on Jordan, it's Smith, Shumpert, or Corver, which LOL. Kyrie isn't helping here as Jordan, Pippen, and Harper all big and athletic. If Kyrie is on Pippen or Jordan, they're taking him in the post and getting an easy two points all night.
In regards to the rules argument, if it's today's rules, the Bulls win. With today's ticky-tack foul calls, Jordan is fouling out whoever guards him and is scoring 50. If it's 90's rules, the Bulls win. The Bulls would body up Lebron, Kyrie, and Love like they've never experienced and I'll take the Bulls mental toughness any day over the Cavs in that situation. Is Kyrie going to out-physical Jordan and Pippen? Is Love going to push Rodman around? Lebron physically could handle it, but I don't think he could mentally.
