Usman had bad defences so the division as a whole is worse?
Gilbert, Belal, Luque, Shavkat, JDM, Brady, wonderboy a few years ago, Garry, even Nyeal, these guys would almost definitely be ranked top 10 a decade ago
Aldos losses at featherweight are bad becuase he immediately went on a title run at bantamweight arguably getting 4 top 10 wins
Volks losses to islam aren’t a factor becuase they were at lightweight, and if he does go on a skid and has no success from here on, it can be excused more becuase if someone as good as volk was isn’t winning anymore, then you know he’s done
