Always tough to gauge an ambiguous question like above. Is a big puncher the same as a KO artist? I guess you just try to find some kind of balance between "natural hitting ability" and success at the world level. So who do you think carries the biggest punch at 140 pounds? Regis Prograis obviously comes to mind, receiving a push amid the WBSS. Taylor's got a nice KO ratio going for him. Baranchyk? My heart tells my Troyanovsky but can you really give the honor to someone who is a notch and then some below elite? Couple years maybe it'll be Dadashev or Jukembayev. Got me thinking about Ritson. Ohara Davis would tell ya it's Ohara Davis.
