Boston Celtics assistant coach Lawrence Frank interviewed Wednesday for the Detroit Pistons' coaching vacancy, according to NBA coaching sources.
Frank, formerly coach of the New Jersey Nets, is the second candidate to be formally interviewed for the position, sources said, joining former Atlanta Hawks coach Mike Woodson.
The Detroit News and Detroit Free Press reported in Thursday's editions that the Pistons also have scheduled an interview with Milwaukee Bucks assistant Kelvin Sampson by week's end.
The Pistons need to replace John Kuester, whose long-anticipated dismissal was announced June 5 after the team was formally sold to California billionaire Tom Gores. Kuester posted a 57-107 record in two turmoil-filled seasons as Pistons coach.
The Pistons have likewise requested permission from the Dallas Mavericks to interview assistant coach Dwane Casey, who was taking part Thursday in the Mavericks' championship parade in Dallas.
Casey and Frank are the two finalists for the Toronto Raptors' coaching vacancy. Both were also finalists in Houston and Golden State for jobs that went to Kevin McHale and Mark Jackson, respectively.
Frank was 225-241 in parts of seven seasons coaching the Nets before joining Doc Rivers' staff in Boston this past season, replacing Chicago Bulls coach Tom Thibodeau.
Casey, 54, has been waiting for a second shot at a top job since being dismissed by the Minnesota Timberwolves with a record of 20-20 during the 2006-07 season.
Casey narrowly missed out on coaching jobs last summer with the Hawks and the Los Angeles Clippers. But his stock has been helped by the Mavericks' run to the championship and his role in masterminding the defense that gave Miami's LeBron James such troubles during the NBA Finals.
Kuester and Woodson were assistants under Larry Brown on the Pistons' championship team in 2004, but Woodson elected to take the Hawks job in the summer of 2004 instead of waiting for the opportunity to potentially succeed Brown in Detroit.
Woodson posted a record of 206-286 in six seasons in Atlanta, advancing to to the second round of the playoffs twice.
Sampson has never been a coach at the NBA level, but stints as an assistant with the San Antonio Spurs and Milwaukee have pushed him into contention for jobs after coaching college basketball at Indiana and Oklahoma.
Ex-Pistons center Bill Laimbeer, currently an assistant coach with Minnesota, also has been linked to the Pistons' opening.
