Floyd Mayweather Paul Williams Miguel Cotto Antonio Margarito Joshua Clottey Shane Mosley Zab Judah Even a fringe contender like Kermit Cintron would be a top level fighter in todays 147 division and Clottey would fight Spence, Thurman and Crawford for #1 today.

Can you picture Margarito vs Thurman? Thurman would get folded mid to late rounds from the pressure and body assault. Spence and maybe Crawford (we need to see him at 147) are the only two who can do anything in this era.
