Has he fought anyone like Ball? Ball is like this little meatball of muscle who never stops coming forward, makes everything as rough as possible. fantastic fight.
Inoue getting dropped by Cardenas, who is not a world-level fighter, shows he's getting near his weight limitations. A genuine elite featherweight like Ball would bully him, rough him up and could walk through his best shots because of his size. Inoue is a phenomenon, and Ball is nowhere near him on a skill level P4P, but in terms of sheer size, it would be a horrible fight for Inoue, and he could easily lose in a horrid dog fight. He should clear out super bantamweight, and wait for Nakatani - that's the megafight. If he beats Nakatani and Bam, he doesn't need to go up any more weight divisions and cements himself as the best fighter of the 21st century, except Floyd.
