I am sure it has been stated already... But my take on it is this.

You got Casa as champ. All-be-it a champ who has had a couple gifts. Now a dethroned champ. Now JMM beats him up... convincingly...

You've got J Diaz... He clears out the division loses to Nate. Kudos Nate your the champ.

So its the man who beat the man(JMM)... vs the man who beat the man who beat everybody (Nate).

Pac came in there and beat a somebody. And, although Pac beat JMM in another division AND only slightly (or not according to some) you have to give JMM credit for beating a tougher bigger stronger higher ranking opponent.

As for P4P that is where you'll see Pac above him until JMM gets the Win...
