I like this, "All of Fedor's best wins are against HWs that were smaller than him.". Really? Lets see.
Fedor: Height 5' 11", Weight 220-235lbs
Best Wins: (Weight at time of fight)
1) Big Nog: Height 6' 3", Weight 230lbs
2) Cro Cop: Height 6' 2", Weight 225lbs
3) Big Nog 2: Height 6' 3", Weight 235lbs
4) Arlovski: Height 6' 4", Weight 240lbs
5) Sylvia: Height 6' 8", Weight 265lbs
6) Hunt: Height 5' 11", Weight 290lbs
7) Schilts: Height 6' 11", Weight 255lbs
8) Herring: Height 6' 4", Weight 250lbs

18) Ogawa: Height 6' 3", Weight 250lbs
19) Goodridge: Height 6' 2", Weight 240lbs
All except Arona, Lindland, and Randleman are significantly taller(2+in.) and/or heavier(10+lbs) then Fedor AT HIS HEAVIEST. And for the, "Yeah, but they are smaller than today's HW" crowd. Most of today's top HWs are between 235 & 255lbs. 11 of the opponents listed are 235+lbs.
