Pac would've been knocked out and in left in a bad state for quite some time had he squared off with Duran. The way Pac tends to get hit flush would be disasterous against a guy like Duran, who was an expert at timing and landing big, clean shots inbetween faster guy's flurries.
Duran would smack Floyd around fairly easily. But then again, Floyd would never sign to fight a prime Duran.
True Floyd would never ever EVER sign a fight with Duran he'd be too scared to even meet him and shake his hand
Pac had about 2 years where he would have given the best Duran a damn good fight...still would have to pick Roberto however.
