LOL!
1. Shaquille O'Neal is not part of that era, neither is Mutombo(drafted in 1991) or Alonzo Mourning really. Anyway are we talking about the same Alonzo Mourning that was barely 6'10 and usually got his ass kicked by Luc Longley?
2. Tim Duncan is better than everyone you mentioned.
3. Dwight Howard is a much better defender than someone like Patrick Ewing.
4. Shaq played in the modern era.
5. Don't make it sound like Bill Laimbeer would be anything special in this era. He is no better than Joakim Noah, Bogut, Chandler etc and not even close to say Ben Wallace. Laimbeer was basically a 10/10 guy with about 1 block per game.
6. Kevin Garnett is every bit as good a defender as David Robinson and pretty much the same size.
Tim Duncan, Kevin Garnett, Shaquille O'Neal, Dwight Howard, Yao Ming, Ben Wallace >>>>>>>> Olajuwon, Robinson, Ewing, Laimbeer, Mutombo
#1. Micheal Jordan played from 1984 to 2003. He won his first title in 1991 (Mutombo) and his last in 1998. During the times you list when Jordan wasn't part of that "Era", Jordan won 6 titles, was MVP 5 times, and was 1st team all defense 5 times.
#2. Duncan played when Jordan played.
When Jordan won his last title, Duncan was a rookie who averaged 21 and 12.
When Lebron won his title, Duncan was 17 and 9.
In fact, Duncan's best years came when Jordan played.
#3. Source: Basketball reference.com
The difference between Ewing and Howard's defensive rating is .9. Ewing is 20th all time on defenders. Howard is 17th. Ewing was in the top 3 in the league 6 times, Howard 5 times. This is basically a draw and a poor point.
#4. Shaq came into the league when Jordan won his first title in 1992. They played together for 9 years, excluding the 2 years that Jordan took off. As above, these were Jordan's "best years"
They were also Shaq's best years, when he never averaged less than 23 and 14 (his rookie year). No center in Lebron's career has approached the impact that Shaq made in the game during Jordan's big years.
Oh they also won gold medals together in 1992.
#5. Bill Laimbeer finished in the top 10 in rebounding for 7 times and was in the top 5 5 times. He is largely considered one of the dirtiest players of all time. In the current NBA he would have been one of the scrubs you mentioned, but that is because of the way the game is played now not because of the player he was. In the time that Jordan played, he was an enforcer who would destroy you if you came into the paint.
#6. I agree here, except that Garnett isn't a center.
Robinson:
#4 all time in Defensive Rating
#5 all time in block percentage.
#4 all time in blocks
Was in the top 5 in defensive win percentage for 12 years
Never finished less than #10 in PER and was only outside of the top 5 twice
To be blunt, David Robinson was better than Duncan because he was so good at defense.
But lets compare Kevin Garnett, who isn't a center:
#19 in all time Defensive rating
#63 in block percentage
#19 in blocks
#7 in defensive wins (right behind the Admiral)
Top 5 in PER 5 times
It is close and the steals are way in Garnett's court (which is why he is close in defensive wins). But overall, steals aren't guarding the paint, which was my entire point.
So fixing the fact that you have Duncan in who has played limitedly with both players and putting Shaq on the side he actually played on.
Garnett (not a center), Howard, Ming, and Wallace against Shaq, Hakeem, Robinson, Mutombo, Ewing, Mourning, Laimbeer
Wow you could not have proven my point more if you had said it.
