However, similar to what you have mentioned, it will certainly be very difficult for Casimero to get the fights that his career will need to become a deserving challenger for Naoya Inoue. This might not very much be important if the boxer is young and only on the beginning of his career. But this Casimero is old for a boxer and on the ending of his career.
Also, there might be fans of Casimero who will mention Pacman and Casimero might also continue to fight in his 40s. I will be shaking my head in this argument because Pacman a different type of boxer and a different type of person. Casimero might fight in his 40s, however, will he get a victory similar to Pacman against Broner or Thurman? Casimero will not, I reckon.
