Two of the best rebounders in the NBA sat about 10 feet from each other in the Chicago Bulls locker room Friday night, smiling about a 100-99 overtime win over the Celtics, but in awe over what it took to get there.

Joakim Noah and Carlos Boozer, who entered the game ranked eighth and 12th in the NBA with 10.7 and 9.7 rebounds per game, respectively, had worked unusually hard for a game against the NBA’s third-worst team in rebounding differential (minus-3.8).
