You beat me to it Bro, I was about to say that.
If PAC can improve his balance when he tries to recover from his lunging straightleft he is pretty much a Tank.
At this stage in PAC's career there is not much to change from him anymore other than maintain his top conditioning and improve his balance.
All in all though he is much improved:
1. His defense improved he was blocking alot of JMM's punches with his gloves.
2. Though still lacking his balance has improved as compared to before.
3. Right hand is big time improvement.

PAVLIK:
Permeable Defense and sometimes plodding.

COTTO:
Not perfect defense but who has, other than PBF

I disagree a little about Pacquaio, I think that Pacquaio's defense looked horrible in many parts of his fight against Marquez, he was getting hit by punches he shouldn't have many times in that fight. One other thing I noticed was that Pacquaio needs a lot of space to throw that left hand, and Marquez would move back, then come forward just a little too close for Pacquaio to throw that left hand like he wants to which in the early middle rounds I felt stopped Pacquaio from throwing very many punches.

That's your opinion Mr. TAE.

If Pac's defense was that horrible, then he would've been KTFO or KDed by JMM.

... he has a good chin obviously... he was getting picked apart for a lot of rounds. I was jush surpised because Barrera fought MArquez pretty evenly, and in Pac-MAB 2 Barrera wasn't landing anything, and Pacquaio was completely dominating that fight though he never stepped on the gas.
