If I'm Nakatani I'm looking at this as the ultimate fight to aim for if he chooses to move up from bantamweight at some point. I don't think Inoue will be at 122 for too long, so I can see this being a featherweight superfight in a few years. It's a fight I think both guys would take, especially in a few years when Nakatani is around 30 and Inoue is older. If they fought tomorrow I think Naoya would smoke Nakatani, but in the future it could be very competitive.
I like both but on a P4P basis Inoue is a class above, plus Inoue is vastly more proven at the higher weight classes.
