Lawrence Frank walked quickly toward midcourt as the final seconds ticked away, greeting Doug Collins with a handshake and a few words. Frank's future is uncertain in Detroit and Collins is on his way out as Philadelphia's coach. That's what happens at the end of a disappointing season. Greg Monroe had 27 points and 16 rebounds, and the Detroit Pistons made the most of their home finale by beating the Philadelphia 76ers 109-101 on Monday night. For both teams, the game was overshadowed by uncertainty off the court. Collins won't be back as Philadelphia's coach, and Pistons owner Tom Gores remained noncommittal before the game on the status of Frank, his coach, and Joe Dumars, his team president.
