Lebron, Jordan and Kobe beat some of these teams in the playoffs.

I did some research on some well known defensive teams using "difference from average DRTG" a while back and I was kinda surprised the 90's Knicks were that high.

60's Celtics were far and away the most dominant defensive team ever. Multiple seasons where they flat out dominated.
