Personally I think Penn is an amazing fighter and can take anyone down in
his weight class. Fighting against GSP I don't think he will pull it off. Don't get me wrong, it will be a great fight, one to remember. GSP is just too good. Dana said whoever wins (GSP is going to win) will fight Thiago Alves. That's another fight to look forward to and if GSP wins he will work his way to fight Silva and probably lose. Unless of course he trains like crazy and some how gets himself up to Silva's caliber.
Kind of a side discussion for this topic, UFC portrays their fighters as being respectful and classy. Sure they have some fighters with these qualities, but it is fighting, when people fight they let their emotions get the best of them. A lot of fighters make rude and sometimes obscene gestures and on top of that there is a lot of trash talking going on now a days. It's almost getting to be a male soap opera like WWE.
Anyway, If you like to discuss MMA I visit a forum called
mmachump.com It's a pretty decent website with a crowd of nice guys.
