I'm thinking at 147 in the pros he'd have been fighting ODLH and Sugar Shane Mosely and Trinidad and Vernon Forrest and Fernando Vargas and Mayorga and I don't see things going his way mostly in that environment. But then maybe I've got the years wrong.
KT retired in 2005. This is who was ranked by ring end of year at 2005, IF he had moved up before the Hatton fight. Zab Judah, Champion Antonio Margarito Cory Spinks Shane Mosley Luis Collazo Thomas Damgaard Kermit Cintron Jose Antonio Rivera Oktay Urkal David Estrada Carlos Manuel Baldomir
Of course, he could have moved up before that. I think it would have been much tougher had he gone up in maybe, 2002-2002.
