Not really,he's had 3 years to ask for a rematch,why ask Pac when he's busy and why the heck is Pac going to fight MAB,Larios and then EM. There was always going to be a third EM fight after the second one if Pac won,EVERYONE knew that!
To say MAB won all 3 clearly is nuthugging of the highest order MAB won the first(em GOT IT),lOST THE SECOND(mORALES WON THAT clearly)but got the decision and the third was called a draw by US and UK commentators sooooooooo

True that,MAB in his prime would take Pac to war and IMO win but that's the point,he is no longer in his prime therefore Pac would most likely win.
