If anyone lost it was gonna be the Pistons, not the Bulls. Bird wasn't gonna be out there taking rings in the 1990s.
The big "what if" is what if the USSR had released Sabonis to the Blazers before they destroyed his knees. THAT is a player who could have single-handedly wrecked some of Jordan's title hopes.
Blazers went to 6 with the Bulls in 1992 with a worthless

Kevin Duckworth at the 5. How many titles would they have won from 1990-1996 with a prime Sabonis in that spot instead?
Detlef Schrempf said repeatedly that if Sabonis had been allowed in the league, he would be the best player in the NBA. He was seeing him play in person in Europe and calling him straight-up better than anyone in the league while Jordan, Magic, and Bird were all playing. Donnie Nelson said he was a more athletic Bill Walton with a better shot. George Karl said he was the best guy in the world outside the NBA and the guy any NBA team needed to chase if they wanted to win a title. P.J. Carlesimo said there was no limit to how good he could have been. Bob Whitsitt is the one who scouted and recruited him, and he said he could have had a Jordan-like impact on the game. And Bill Walton himself?
This video is misleading because he was actually injured for a lot of the games they show here (he played the entire 1988 Olympics injured), but watch an injured Sabonis giving that work to David Robinson. Sabonis is basically the reason the Dream Team had to be created.
Even old, hobbled Sabonis could give the Bulls that work:
Those Nike calls MJ was getting at 3:10 and 5:32 though.
All sorts of guys big-upping Sabonis:
Adding Sabonis to those 1990s Blazers teams would have been almost on the level of a Durant to the Warriors level impact. The Blazers were already 60+ game winners and a contender with a terrible center, now they'd be wiping the floor with one of the best centers in the league. Look at how awful the teams were that were built around Hakeem and Robinson at the time, then imagine Drexler, Porter, Kersey, Buck, Cliff Robinson, Danny Ainge, and Drazen Petrovic with Sabonis in the middle.
