i dunno,spongy....you got different weight classifications involved here.......is henderson moving down in weight to fight silva?(sounds doubtful as he has actually fought at heavywt).....
i`d surmise that silva would be moving up and would be fighting a naturally bigger guy that`s very hard to stop.....even though henderson isn`t a huge lt hvywt,he`a s a good deal bigger and probably stronger than silva...
so,in that scenario,i`d probably lean to henderson to wear down silva in a grueling kinda` fight...i know that silva`s looked unstoppable,but,can you picture rich franklin beating rampage jackson?.....i can`t...i think he`d run over franklin....
silva`s beating the leben`s and the franklins...while henderson fights guys like jackson,vanderlei silva and the brazilian submission monster that fought fedor hammer and tong several times(his name escapes me)....
the size difference in a 5 round fight would favor henderson a tad,imo....if silva`s moving up....
