I am a pac-fan but i gotta say yes i think hes not invincible but the point in my mind is that JMM was the past hes constantly evolved and add the fact the pacquiao didnt have a decent right hook when he fought JMM. The same right hook that took down the fighter known as Ricky Fatton rofl. I admit i haven't seen a JMM fight lately but i think JMM hasnt improved by leaps and bounds lately since age comes into play. But look at it this way, JMM has been KO'd by manny 3 times when he was still an unrefined brawler (IMO) and what would you think will happen when the JMM whos improved slightly fights the Pacman whos improved like he was a pokemon evolved? I dont know but we have to really see that fight to really know what will happen but in a logical point of view that wouldnt be good for JMM.
