At heavyweight, Brendan Schaub’s third-round TKO of Mirko “Cro Cop” Filipovic sends Cro Cop out of the top 15, vaulting Schaub to #11 (over a fading Cheick Kongo) and brings former top-10 stalwart Josh Barnett in at #15.
At light-heavyweight, new UFC champion Jon Jones vaults from #5 to #1, dropping former champ Mauricio “Shogun” Rua to #3, below new #1 contender Rashad Evans (though, I must admit, I think their P3Y records are just about even–I have Evans the edge for more and more recent wins over top-10 fighters).
At featherweight, Erik Koch’s first-round KO of former #7 Raphael Assuncao sends Assuncao out of the top 10, bringing in Chad Mendes.
