In his one season on Doc Rivers ‘ staff with the Celtics , Lawrence Frank  picked up the mantle from Tom Thibodeau  as the team’s top assistant and lead defensive coach and returned the team to the top of the defensive rankings. The Celtics led the NBA in points allowed, were second in field goal percentage defense and finished in a virtual tie with Thibodeau’s new team — Chicago — for points allowed per 100 possessions.
Frank spent much of the offseason interviewing for head coaching jobs in Houston, Golden State and Toronto, and now it looks like he has found a new home. Yahoo’s Adrian Wojnarowski is reporting that Frank has emerged as the Pistons’ top choice and is expected to receive an offer in the next 24-36 hours.
Wojnarowski also reports that Frank is expected to bring along Roy Rogers, who came over from New Jersey with Frank and served as the team’s big man coach last season. Frank compiled a record of 225-241 as head coach of the Nets  that ended after a disastrous 0-16 start to the 2009-10 season. But Frank’s reputation as a dedicated, hard-working coach followed him to Boston and he was able to forge strong relationships with the team’s veterans.
The Pistons were a disaster last season under coach John Kuester , especially defensively where they ranked last in field goal percentage defense and 28th in points allowed per 100 possessions. Only Cleveland and Toronto were worse. There were also reports of an attempted player revolt against Kuester , making Detroit one of the most dysfunctional teams in the league.
Frank will have his work cut out for him as the once-proud franchise is digging out from a series of bad contracts and mediocre results. But team president Joe Dumars pulled off a coup when he drafted Greg Monroe in 2010, and a young nucleus of Monroe, Austin Daye, Jonas Jerebko and rookie Brandon Knight  is reason enough for optimism.
Rivers and Danny Ainge will now be in the market for an assistant coach to round out the staff, and they will also be looking for supporting personnel to replace Rogers and Darren Erman, who left to take an assistant coaching job with Golden State. Erman was with the team for the last four seasons.
