The more interesting question is "which brothers have a wider gap between them (the greater one and the lesser one)?" IMO, the gulf between Wladimir and Vitali is a good deal wider than the one between Juan Manuel and Rafael. Others won't agree.
Marquez bros have accomplished more against better competition and given us some of the best fights in history Marquez's bro's. The Klit's shouldn't get knocked too hard though there terrific HW's not there fault the division is so weak at the time.
:shock:...:nono Pongsaklek Wonjongkam...brothers? No, just Pongsaklek Wonjongkam. He's all you need. P-Won>both Marquez bros and both Klitschko bros. I would do things to them that would make Ron Jeremy go "You can't film that smut!". Followed by me asking why he is even there and asking him to leave.
in an actual fight, obviously the klitschkos. but in a p4p sense, gotta be the M bro's. k2 have never been in the top 10 together. a couple of years back, rafa and juan where dead certs in the top 10.
TBH, I'm trying very hard not to be biased for the Marquez bros as I love them so I went with the Klitschkos. Looking through it I see them as unbeatable for the moment and they pretty much rule the division. JMM does have a case for being the man to beat at lightweight though. Even RM had his run at bantamweight. This voting takes some thought but I'll just vote for the Klitschkos.
