The Thomas & Mack Center at UNLV was host Thursday to the latest iteration of Team USA, a collection of basketball talent so deep and so dense that its superstars don’t even need last names. Yet on a night when the Americans cemented their status as Olympic favorites by blowing the Dominican Republic to smithereens in a one-sided exhibition, it was the coach on the losing end who somehow managed to steal part of the spotlight. Such is the genius of John Calipari, the Kentucky coach who has moonlighted for the past two years on the FIBA circuit. The game itself had his fingerprints all over it, most notably in the form of Anthony Davis, who made his Team USA debut mere months after leading the Wildcats to a national championship. When Davis sank a 3-pointer in the fourth quarter, he turned toward the Dominican Republic bench and woofed at Calipari. “He was telling me that I never let him shoot threes at Kentucky,” Calipari said.
