kumusta ka na Pacfan?

I'm not rooting for either fighter. However:
If I could envision a Pac victory: Pac darts in with 4-5 punch combinations from the start of the bell and finishes each round doing the same.

Punch rate means everything- he has to end every round with a flurry to impress the judges.
Anticipate the laser right hand. This means Pac will have to exhaust twice as much energy as PBF.

When he fought MAB I-- there was some head butting- MAB complained. I'm not sure how much of it was positioning or possibly intentional. I say employ that strategy every time PBF tries to clinch (and he will) Use his head as well as his fists to try and bust up PBF. That is the only way I could see him getting a stoppage. PBF has an underated chin. But he cuts like anyone else.
