Eloy Vargas received the feed pass on the left block. His defender, and assistant with the Dominican Republic national team, pressed against him with arms stuffed inside bulky pads. Vargas made a faint attempt at faking left before spinning right. Before he could even release a baby hook, the assistant had interrupted. “Nope,” the assitant coach said. “You gotta sell it going left harder. Come back, do it again.” Vargas did, this time giving a heavier feign before spinning.
