Physicality is one variable of defense. You could do more, but a lot of the guys "doing more" couldn't really do much else. Why teams were still scoring 106ppg until 1991 (and this is with significantly less +EV 3's being taken) Yeah, John Starks or Craig Ehlo could be more physical with MJ than Iguodala or Kawhi can be with LeBron. But it's still John Starks and Craig Ehlo. This is why plenty of guys that aren't Jordan were able to score tons of points then, because the defense was bad.
Just because someone elbows someone in the gut once every 5 minutes doesn't make it great defense.
As far as the Pistons go, the NBA has done a great job of marketing that as this Little Brother beats Big Brother narrative where MJ was finally able to overcome his foes and rise to the throne. When in reality, all that really happened was the Pistons got old and the Bulls got better. They slogged through the regular season with 52 wins and almost lost to the Reggie Lewis-led Celtics in the rd before.

People cite the 80's Pistons as this notch on MJ's resume when he didn't even beat them. That's not historical accuracy, it's Nike marketing.
There's become 2 MJ's over the years. The one that is the best/most accomplished player of all time by most reasonable metrics, and then the Nike Jordan that is basically this superpower that played with weak teammates, played the toughest defenses ever compared to his soft predecessors and beat the most stacked, toughest era of the NBA ever. The ladder is not a real person. It's just Nike/ESPN marketing
I don't really care but it has been pretty jarring to watch large portions of the NBA's history and the evolution of the game just get totally distorted because one guy needs to be built into a God-like figure so idiots will spend $500 on shoes.
