Aldo has been mainly working with his cuban coach when it comes to boxing. And cubans have arguably the the greatest defense in boxing ever. The cuban school of boxing is almost military like and they perfect the art of defense. Current champions who arguably the current best pure boxers today are Guillermo Rigondeaux and Erislandy Lara two guys that are virtually impossible to hit clean. Hope Aldo comes in with that mind set in the mcgregor rematch cuz if he does he can make it a very easy fight on himself.
