If we were to argue what his best aging win is (what the opponent did after their loss), we could argue Ryoichi Taguchi as he would become a unified champion after his loss to Inoue. I would agree though that Fulton is the best aging win especially if Fulton beats O'Shaquie Foster in his third weight class in this rumored next match. https://www.boxingnews24.com/2025/0...n-gervonta-davis-vs-lamont-roach-2-undercard/
Wins that aged pretty well for Inoue: Fulton Taguchi Andrew Maloney Rodriguez First Donaire win. All of these fighters wound up winning titles after Inoue beat them.
