What's hilarious DFS is that I am all about Defense and I probably overcompensate for that when judging careers. Like "I love Mutombo irrationally, but that's probably because I overvalue defense, so I'll dial him back a few notches on my NBA totem pole."
Best post defenders in recent memory in the pros (post 1990): Olajuwon, Mutombo, Robinson, KG. Second tier: Mourning, Wallace, probably Howard. Third tier: Ewing, Rodman, Ibaka (still young), Luc Longley (kidding). Apparently Theo Ratliff belongs in here, but I don't remember that part of the 2000s.
Best perimeter defenders: Payton. Jordan, Pippen, probably Kobe (although it drives a stake through my heart to admit it). Tier 2: Dumars, Kirilenko, Stockton, Battier. Tier 3: Alvin Robertson (what? that's right, I said it), Tony Allen, Iguodala maybe (I haven't been following him long enough to know what his perimeter D was like before last year when all the irrational trade rumors started).
Disqualified for being an evil cheating son of a bitch: Bruce Bowen.
Just don't ask me to lump those guys in Bill Simmons style with guys who played so-so D, because I can't be fair.
PS anyone who says Stockton wasn't a SOB on D doesn't remember 96-98 playoffs very well. He was borderline cheapass, but he got the job done. Nobody liked playing against him.
