yeah , Matt has fallen off considerably Serrra > Huges . Id so rather trrain with Serra in my corner any day . Im not even a Jits guy , and my style is totally closer to Hughes , but Serra is just more complete and sees the whole game better .
Cheik Congo is improving vastly. I remember not too long ago he was getting tooled by Carmen Morera (?) for lack of ground game. He's to the point where on the ground he doesn't appear lost.
In reference to Matt Hughes, it seems like team Miletich in general has taken a bit of a stumble. Who is currently on their roster poised to bring them glory? American Top Team seems to be coming on strong as is Greg Jackson's team down in New Mexico.
At this point he's lowered in the rankings due to inactivity. It's hard to call a guy over-rated who has won almost every professional fight he's been in at the elite level including all of his #1 contenders. He thrashed Nog when Nog was considered #1. He beat Cro-cop when Cro-cop was a feared force. There have only been a handful of times when Fedor has been in trouble and he's always come back to prevail. I think his only loss was to Tsyoshi Kohsaka from a cut caused by a headbut back in his "Rings" day. In the return bout, he absolutely destroyed Kohsaka. Nobody in the heavyweight division has quite a similar resume.
With his convincing victories that avenged his two losses, I would have to say
GSP is on top right now. A rubber match victory with Serra would make it almost without question.
