Dont think Pryor fought at 147 ever. Mayweather had more than 2 fights at 147.... he beat Mitchell, Judah, Baldomir & Hatton. :good
he fought at 154...i wouldnt consider him a light middlewieght no how. just say it was a mistake and that you meant LIGHT-welter he is so awkward he threw almost 80 - 100 punches a round, could punch and set up his attack in a boxing manner. he is an awkward and rare boxer-swarmer. he had a snappy, hard jab and countered effectivly but was coupled with a fast paced combinations. this was a typical style in the U.S. amatuers at the time, take a look at lee roy murphy who was in the same camp for a while. both had a low defence but threw alot of punches and were counterpunches...waited for the right hand they span away from it and came back with a lead right cross...in pryor case he follwed every counter with a left rigth left right. i think he could get beat by a good poxer puncher to keep the distance and to knock him back if needs be. but no one at the time was willing to give him an opertunity. he was a good draw in only Cin-city. he wasnt really ducked, but avoided you did have a chance against him but why risk a loss on his own turf when you could fight mamby...there is a reason bruce curry fought leroy haley when he was ranked number 2 in both bodies. i dont think he is underated or overated he was just strick down with the crack/coke epidemic at the time...half of the mid 80's and early 90's contenders and champs used cocaine, either it was leonard to pinklon to benitez to duran to dokes to snipes to chavez to pernell to comacho etc etc etc etc etc etc etc.
I doubt anybody would argue he's the greatest welterweight of all-time, especially seeing as he's a light-welterweight, but anyway. He wasn't amazing, but he was a very good fighter - a great fighter. His style wasn't about having an amazing defence, it was about punches in bunches, strength, exerting pressure and endless stamina. He had all these in abundance.
One of the sources I was using called him a welterwight so I had assumed he fought there at least once. I said in my first post I don't no that much on him but what iv'e seen on youtube etc and looking through his record didn't seem that impressive. But it seems a few people agree whilst being a good fighter didn't really have the resume to back up the skills he possessed.
