I saw a picture of Chavez next to Amir Khan recently and he dwarfed him. I guess Chavez is 6'1, Khan roughly 5'10, but it looked a much bigger difference than that. I'm surprised a Cotto/Chavez fight is being mooted given their respective heights & weights - Cotto is about 5'7'' and appears to be fighting above his natural weight class even at 154, a move to 160 wouldn't do him any favours. And Arum has already said that Chavez can't move back down. Even at a catchweight of, say 157, it would be a strange matchup.

Not saying Cotto wouldn't beat Chavez (although I think it'd be closer than most suggest due to the size differential) but there are plenty of fights at 154 or 147 with massive appeal for him (assuming he can still make 147).

Martinez seems desperate for a Cotto fight... if he agrees to 154 then that is the fight Cotto should really go for in the summer after the DiBella's March date (with Maravilla seemingly against either Chavez or Macklin). One of Alvarez or Kirkland at 154 would also be very interesting, but also difficult to make due to the promoters. Mayweather could still be a realistic possibility should the Pacquiao fight not materialise, although I feel that fight should have happened about four years ago.

No-one is mentioning JMM, but if they could agree a weight I think that would be a cracking fight given that they are roughly the same height. Both are listed at 5'7'', and they are pretty much the two biggest names out there other than PBF and Pac. Then there's the Mexico/Puerto Rico rivalry. Plus it shouldn't be too difficult to work out promotion-wise. Winner would be first in line to face the PBF/Pac winner. It makes perfect sense to me, especially after JMM's performance near the WW limit against Pac last time out.
