This is a weird match-up. Chavez Jr. is no Sergio Martinez or Bernard Hopkins. The two people to beat Pavlik. If Pavlik's loss to Sergio was due to being drained for the fight and his people believe that with a proper nutrionist, he would be fine at 160 at least against Chavez Jr, so be it. I guess from Pavlik's standpoint, Chavez Jr. is a big pay day, if he's going down the hill, then at least get paid a lot doing it. If he's not going down the hill, he makes a lot of money on a comeback fight and then challenges Sergio. From Chavez's standpoint, it's a big name to have on his resume if he wins and the win probably opens up a lot of doors, and if he loses, he lost to a top dog in the division, not too bad a loss.
