Carmelo Anthony breathed a sigh of relief about moving on from the Celtics and the physical nature of their play. Wait until he gets a look at the second round. The Pacers, who dispatched the Hawks in six games — as the Knicks did to the Celtics — are big, physical and well, big and physical. They also led the league in defensive field goal percentage and were No. 1 in the East in fewest points allowed. “They’re big they are well-coached,” Kidd said. “They’ve got some all stars over there. [Paul] George is one of the top players in the league and they’re a great defensive team. “We’ll take a look at them [on film] tomorrow and get ready for a quick turnaround.” Real quick. The Knicks and Pacers, with a proud history than includes Patrick Ewing and Reggie Miller and the Davis lads and John Starks and Spike Lee — resume the playoffs with Game 1 of the second round tomorrow in the Garden. “We’ll break down the Pacers tonight and have a game plan in place,” Knicks coach Mike Woodson said. “Then we’ll be off and running on Sunday.” Literally. The Pacers do like to push the ball with guards George Hill and Lance Stephenson plus triple-double threat George. And up front, for all the physical stuff Anthony faced against the Celtics, he will have to contend with two of the Pacers’ big men, 7-foot2 center Roy Hibbert and 6-foot-9 forward David West.
