MJ didn't need a 20/10 big - don't get it twisted. He did need defensive minded bigs: Oakley, Cartwright, Ho Grant, Worm. Then for good measure he had other less than stellar bigs like Wennington, Stacy King, Luc Longley, Will Perdue, etc. to deliver anywhere from 18-24 fouls per game on players like Shaq, Ewing, Brad Daughterty, etc. to lessen their effectiveness.
Now granted an MJ/Pippen defensive duo is probably the greatest defensive tandem in NBA history. They could guard PGs, SGs, and SFs like a mofo. That is invaluable because if you can dominate the backcourt defensively, put a ton of pressure on them offensively, and lessen the effectiveness of their bread and butter (centers, powerforwards) you win. PJ knew that that's why he used to sick a 21 year old Kobe on a perimeter's best player during Kobe's 1st 3peat. Couple that with MJ/Pippen's offensive ability - which could lead a Ewing into foul trouble, you have a recipe for success.
So I don't buy that crap that MJ won without bigs. He had plenty of them at his disposal on the defensive side of the ball. I already stated that MJ/Pippen were the best defensive tandem in NBA history. Then they added Worm - a player that was versatile enough to check MJ in one game and Shaq in the next. Then he could rebound like a mofo. Not looking at his numbers but I could guarantee you he doesn't average over 10ppg but he is a HOFer (finally) because of his versatilty defensively. You have 3 players that are the best at their positions and they are versatile enough to crossmatch against other players in varying positions - you know what the results were: 72-10.
So please stop with this notion that MJ didn't have help in the pivot. He did - it just was on the defensive side of the ball.
