Anthony Davis doesn’t get many minutes or questions on this summer internship with the most feared band of ballers on the planet, but he was ready when someone asked him about the head-spinning year he’s having. If you can add a gold medal to your national championship at Kentucky and your selection as the No. 1 overall pick in the NBA draft, did you have the best year in basketball? “LeBron,” Davis shot back. Once again, LeBron James is the answer. He’s the only answer to the question: Who’s having the best 2012 in the sport? One more time Wednesday night at these Olympics, James was the counter to the latest sluggish spells that saw Team USA give away almost all of a 14-point halftime lead in a matter of seconds to a scrappy but starless squad from Australia whose only player on the Americans’ level — Andrew Bogut — is back home recovering from ankle surgery.
