10 mma fighters with the best takedown defence?

HW: Fedor
LHW: Kevin Randleman or Chuck Liddell
MW: Dan Henderson
WW: Georges St. Pierre
LW: BJ Penn
FW: Uriah Faber

How does Chuck Liddell not have the best takedown defense the guy? The guy hasn't won a fight one time on the ground and never gets taken down. I'm exaggerated about never winning a fight on the ground, but he almost always wins standing-up or hits the guy standing then grounds and pounds.

I also say GSP is better than Cro Cop and BJ Penn. GSP also never gets taken down. I won't compare fights between Matt Hughes, because BJ Penn in naturally a lightweight. Lets be honest here BJ Penn hasn't really fought anybody in the lightweight division who is good at takedowns and Sean Sherk not on steroids doesn't count. We all know Sean Sherk looked like a bum against BJ Penn not on steroids.
