actually i wouldn't say that Hopkins was a HARDER puncher, i'd say he was a SMARTER puncher, just use all 3 (Trinidad, Hopkins, and Taylor's) fights with Joppy as a reference, Trinidad clearly did the most damage, i think at 160 he could beat

Sturm
Catillejo
Miranda
Abraham
Eastman
Soliman
and possibly Taylor
if not him and DLH could easily rule the 154 division again, just like they did the welterweight division
