Religion may not be the cause but staying late due to bible studies during training deprives Pac of much needed rest and healing. I've read some news that even on the night before the fight the Pastors prevailed that Pac should have a bible study, which deprived his body to recharge. Hence, indirectly it affected his performance.There's a study among call center agents that too much late nights make them age faster by 5 years. That's why Pac's ability to absorbed punches, plus Marquez is stronger and faster now, aided the two knockouts.
Manny used to say that the fight is won in the gym, and he knows this. It's up to him to go back to his old dedication, focus, and work ethics when he was still 24 to 25 yrs old, and not yet famous, and not yet overconfident of his abilities, prioritizing the training over TV shows, bible studies, and accomodating friends. So if Pac should continue fighting he should either stop the late nights bible study or at least do it in the afternoon.
Further, if you can experience withdrawal symptoms when you quit smoking or taking coffee for years then suddenly stop it, how much more when you are devoted to the rosary and doing the sign of the cross for years, doing it before every round; He even used to do it more than once during every round when getting hit. The sign of the cross is a form of communication, a signal to his higher self to protect him. Every time he does it, he connects to his higher self. He finds new confidence, more aware and sharp, and can feel the aura of his opponent. Even make blind punches and hit them.
Then you suddenly stop it-- it shakes the psyche! It affected his awareness or presence of mind. That's why he didn't see Marquez foot when he did the double job, he even hit Marquez' face but only softly 'coz he's already outbalanced. It's like driving a lay up in basketball but not strongly.
A lot of things that happen in the material world occurred first in the mental and spirit world. Can a chair or house be made without first designing it in the mind?
'Dapat di na pinakialaman ng mga pastors yun devotion ni Manny sa rosary and sign of the cross. After all, you kiss the pictures of your loved ones, knowing that they are not exactly your loved ones but just a representation of them. I don't pray the rosary because I wasn't trained to, but I believe that it works for those who pray it. The Buddhist have beads, it's meditative, and meditation is good for your concentration and focus. And sharpness and intuition. That's why it's possible that this time Pac didn't see Marquez' foot blocking his lead foot, didn't see the punch, didn't anticipate it. He lacks sharpness and intuition, he was disconnected from his higher self.
