Who is the best defender among these in their primes?

Guys that are in this list:
-Tim Duncan,Kevin Garnett,Shaquille O'Neal,Dwight Howard,Chancey Bullups,Shane Battier,Tayshon Prince and Bruce Bowen.Alos Marcus Camby

Garnett. Period.

I have KG on the top as well

He's one of the greatest shot blockers,rebounders and defenders of all time.He's strong inside blocker,great overall rebounder,great on post defense,good on ball defense,can get steals and is versality defender.He also won a DPOY

#2 Tim Duncan
#3 Shaquille O'Neal

Dwight Howard is going to be a better defensive center then O'Neal in his prime but not better center or player.That's my opinion

HM:DH12 #4,Tayshon Prince #5,Chancey Bullups #6,Shane Battier #7,Marcus Camby #8

Perimeter: Gotta go w/ Battier if you want length and hands in your opponents face..
Bowen if you want toughness

Inside/Downlow: Camby.
Why? Cuz I said so.

Funny but good choice CBI

Bowen...

but why isnt Kobe on your list?

Kobe isn't good enough at the defensive end
