This right here is Mark Caguioa's training ball (left). Notice it's about twice bigger than the ordinary ball (right). This is probably the secret why Mark has one of the most dangerous crossover dribbles in the league. I tried dribbling it for 5 minutes then when I held the original sized ball, the feeling was different. Parang laruan na lang yung tunay na bola. by the way, Mark generously shares this to the whole team. Sa US pa niya binili iyan.
