Difference between a bum and a legend
Fact that Kuzan can even put this much pressure on Garp's crusty ass while he is in great shape and training every day where as Bum ass Old ass Rayleigh literally had Kizaru like his prisoner preventing him from moving even an inch and Kizaru is like way faster than Kuzan should tell you how much is Garp shit compared to Rayleigh
Or you know just look at this panel
If this was Rayleigh, Kizan is getting blitzed and outpaced as he was keeping pace with fastest Admiral
