To look good on TV. Pac does it on his own, so they guy was just saying, let Pac do it so we can get it on camera.
coincidence. the guy wasn't even trying to communicate with manny. he was motioning to someone outside the ring. you were confused by the fact that pac made a glance at him.
to bring in audiences from the christian demographic. the look on Pac's face was priceless as he was being told to go pray. Anybody remember when Andre Agassi won the wimbledon title? You can see his coaches telling him to get on his knees and start crying.
No he didnt. It's a Pacquiao routine/superstition where right after a victory, he kneels down on the neutral corner, prays and thanks God, before truly celebrating the win. He doesnt start celebrating until he has finished saying a short prayer in the corner.
