Pac does everything with his right hand except to throw power punch. So basically, he is ambidextrouys, and when he can be taught to do switch ffoting when throwing right hand, he could be deadlier. Imafgine, he already KDed both Hatton and Cotto with his right hand.
I can't see any visible signs of Pac injecting himself with drugs. That can only mean one thing - he's got one hell of a makeup artist
