Both of these guys seem to be absolute destroyers...if you can't fight and elect to stand right in front of them and let them whale away at you. Neither shows much class, all straight lines and chins in the air, winging away. Berto/Collazo was just terrible.
That said, it should be a very exciting fight while it lasts.
If this is the top in the 147 division, Armando Muniz should make a comeback. He can't be much more than 63.
