great thread. i'll go with the hawk on this one. pryor had a tendency to shine in his best fights, but it'd be damn close. i think arguello might of been a harder one punch ko artist than chavez, but chavez would break the other guys will with power and pressure. he also had a great chin. even duran said at 135, chavez would have a great chance of beating him, but over 135 he would own chavez. i think so too, and i don't think 140 wasn't chavez's best weight either. pryor SD12 chavez
