I might give the 2009 version of Pac a chance against Floyd,but this version vs Floyd now "even if Floyd is slower" still beats Pac.... Pac had Bradley dazed 2-3 times and still couldn't put him away,and this is all while Bradley not throwing an accurate straight right like Juan or Floyd and being a hittable opponent... The straight right being the money shot to disrupt Manny's rhythm.. Even if we give Pac the unanimous decision against Tim,we know Tim is open for hits,Floyd will not be so open... That leaning forward throwing 3-4 combinations will leave Pac open and off balance.. Still makes a great fight IMO,not saying Floyd will beat him easy,but I think at this point Floyd takes this if this fight were to happen.
It certainly looks like he will win pretty easy if you judge from the last couple of fights. Even though Floyd has dominated everyone he's ever face except, maybe cotto and castillo. However remind yourself what they said about Ali before the Foreman fight and look at the result, the oldest cliche in boxing is always true. Styles makes fight.
More interesting is 2009 Pac vs 2012 Pac and how he has changed as a fighter. I think Mayweather from any year beats either version of Pac.
