LAS VEGAS — After a few consecutive makes, Colin Castleton’s confidence started to show, if one was looking closely. He’s not a very expressive player, but a subtle fist bump and head nod bookended successful offensive sequences. As the game progressed, Jalen Hood-Schifino and other Lakers teammates began clapping him on the back harder and harder, dapping him up with more energy and enthusiasm. These things don’t appear on a box score, but directly impact chemistry, camaraderie and momentum, and are telltale signs that a player is starting to impose their will on the game as their teammates attempt to gas them up into further dominance.
