I was just having this discussion with a friend, and we came to see that Berto showed his greatest improvement in movement, defense and power in his last fight. But in another sense, that only now makes him a true CONTENDER, so we have ordained him a Contender with a Belt. No hating, no qualms; it happens with many limelight/olympic boxers (vargas, juan diaz, etc.). But now is when we get to see what type of boxer he will become. Please remember that David Estrada was once pushed as much as Berto, and now he is a really tough trial horse.

Here are the people I think will help him progress in his career & grow as a fighter.

Luis Collazo
Zab Judah
Alfonso Gomez
Carlos Quintana

Out of these, I would say Collazo is his biggest challenge (depending on which Collazo showed up)

And big props to the comment about using him as a great comeback fight!
