The Pacers prepared for the worst. But it worked out for the best — in every way. Indiana was preparing to go without George Hill, who had missed Thursday’s game with a concussion, but the starting point guard was cleared in the afternoon by team doctors and the league. He started and played 42 minutes in the Pacers’ 106-99 Game 6 Eastern Conference semifinal elimination of the Knicks. “I was very excited,” Hill said. So were the Pacers. “He’s one of our better players and he can do a lot, but on this team, he’s the glue,” said Donnie Walsh, Pacers president of basketball operations.
