I like Pac but seriously,to give him number 1 in all those categories is impossible to do.Not conclusively anyway.He is certainly a contender for biggest puncher but I think Chico Corrales,Darchinyan and Raf Marquez hit just as hard P4P.Handspeed,JC although Pac is darn fast.Stamina:Kassim ouma but Antonio Margarito even more so,upwards of 80 punches a round and all can KO you...that's stamina!Relentlessness,yea prob Pac but there are other contenders too.
Agree with you about the Raheem,I think Pacman would give him a beating and I believe he has the power to hurt him too.
