He is equal to some of the guys on the list but I don't consider all of them to be great. Some are simply very good. Like a TA.
Who would you take off the list?
Take off Dwight Howard. I'm assuming you are doing modern era hence no Russ. Add in Bobby jones and Michael Cooper, great defenders. I'd really wonder about Lebron being on list as well. Great athlete not sure I'd call him great defender.
The Orlando Dwight Howard, before the back injury, deserves to be on the list.
Lebron's defense on those Miami teams was one of the best I've seen.
