I really don't see why everyone dogs on Franklin. Out of the three fighters he is probably overall the best. I would put those three like this, Franklin, Hughes then Liddell. The guy does not have a weak chin IMO, because when was the last time you saw him get knocked out? I think he just has bad balance which would explain the reason why he is able to recover so quickly from being hit.
I think overall these three are three of the best in the world. I think all three would be legit contenders or champs in pride or anywhere else.
