Where does Pacman Rank in your eyes of all timers?

After yesterdays demolition of hatton, i started thinking to myself....im never gonna bet against this guy, he looked amazing, as fast as ever, even more powerful then ever...landing perfect punches...i know hatton seemed pretty rubbish and i still dont think hes the same from the floyd defeat... But it got me thinking...this guy has beat all of the best fighters people could throw at him in different weight classes...ye ok he won a few 50/50's but i mean, he won them at the end of the day and people are always gonna say boxers lost a certain fight.... So where does this guy rank when you compare him to the legends of boxing...people like Ali....some people think floyd is the greatest boxer ever but surely pacmans resume is better? Also if pacman goes on to fight Floyd (after even if u want beating cotto lets just say lol i know its alot 2 say but like i said i wouldnt go against this guy anymore) and lets say he beats floyd at welter......Where would you rank him in boxing history? I dunno how i couldnt rank him as number 1...I know boxing standards have lowered over the years but its hard to compare different eras....just as it is with any sport like football even.... So where do you rank pac now in history...and where would you rank him after a floyd win?
