One day after the NBA regular season ended, coaches changes were aplenty on Thursday.
The Detroit Pistons fired Lawrence Frank after his team stumbled to a 54-94 record with him at the helm.
"We thank Lawrence for his hard work and dedication, but we feel it is in the best interest of the franchise to make a change at this time," Pistons President of Basketball Operations Joe Dumars said in a statement. "Decisions like this are never easy and we wish Lawrence well in the future."
Frank came to Detroit before the 2011 season. His ouster had been widely expected, especially after during a stretch in which the Pistons dropped 27 of 36 games in the second half.
The Pistons haven't reached the playoffs since the 2007-08 season.
In Philadelphia, 76ers coach Doug Collins quit after three seasons, though he'll remain an adviser with the organization.
Collins has one year left on a four-year deal worth $4.5 million. The Sixers missed the playoffs after going 34-48.
"This is his decision," team owner Josh Harris said Thursday in announcing the move. "He is not being pushed out."
In Cleveland, Byron Scott was fired by the Cavaliers after the team concluded a 24-58 season -- 14 games out of the playoffs.
Scott, 52, was 64-166 since being hired on July 1, 2010.
"I have tremendous respect for Byron professionally and a great deal of admiration for him personally. At the same time, it is critical for where we are as a team to ensure that we capitalize on every opportunity for development and success and we have fallen short of that on the court," said Cavaliers general manager Chris Grant. "I believe we needed to make this change in order to get to a better position to achieve our goals."
The Cavaliers finished the 2012-13 season with the third-worst record in the NBA.
---Los Angeles Lakers coach Mike D'Antoni will return next season, general manager Mitch Kupchak told the LA Times, likely disappointing fans hoping for a reunion with former coach Phil Jackson.
"Yeah, he's back. I think he's done a great job," Kupchak told the paper. "There's been no discussions otherwise. He's made adjustments. He's been flexible. He's evaluated how he coaches as the season's progressed. He's listened to the players. He's very easy to work with and we think in particular since the meeting the day of the Memphis game, yeah."
The Lakers are 40-32 since D'Antoni replaced Mike Brown five games into the season, though they are 28-12 since a team meeting in Memphis in January.
---Dallas Mavericks guard O.J. Mayo said he will decline the player option for the second season of his contract as he seeks a long-term deal.
Mayo, who signed with the Mavericks as a free agent last offseason, could have returned to Dallas for $4.2 million. The 25-year-old averaged 15.3 points, 4.4 assists and 3.5 rebounds.
"Getting something long term, locking something in is what I think is best for me," Mayo said Thursday, according to ESPNDallas.com.
That doesn't preclude Mayo from returning to the Mavs. Coach Rick Carlisle said Mayo has the potential to be a building block for the franchise going forward.
---The NBA unveiled an anti-flopping disciplinary schedule Thursday that will be used during the 2013 Playoffs.
In the postseason, players will be fined $5,000 for a first offense, $10,000 for a second, $15,000 for a third and $30,000 for a fourth. Beyond that, a player is subject to an increased fine and/or suspension.
The league defines flopping as a physical act intended to gain a foul call on another player.
