The panorama at 140lbs.

Just imagine a tournament between these four champions. You have Regis Prograis (WBC) , Rolando Romero (WBA), Subriel Matias (IBF) and the newly crowned champion Teofimo Lopez (WBO). It would be one hell of a tournament and if I would predict a winner it would be Teofimo Lopez winning the final against Regis Prograis. The other two champs Romero and Matias I see as weaker champions but of course I can be wrong, there is only one way to find out.
