Darren was hitting his outside shot and the Pacers were not stopping the ball in transition, so Collison thrived. He was also playing an old team. His pairing with Rondo didn't look much different than usual. Cousins going inside more may have helped that pairing by getting a sucked in defense for open threes. The Pacers don't have any guards that will post either up as well. For his size, George Hill would rather face up than go low. So the defensive switching issues didn't present themselves often.
