There were plenty of coaching jobs to be had in the NBA on Thursday morning, but there are quite a few less on Friday.

The Indiana Pacers and old friend Larry Bird, Pacers President, announced that the team has hired former Celtics coach Jim O’Brien as their new head coach.

In four years with the Celtics O’Brien compiled a record of 139-119 (.539) with playoff appearances in 2002 and 2003, including a trip to the Eastern Conference Finals in 2002.

Billy Ball in Orlando

Billy Donovan, who is coming off of his second straight national championship at the University of Florida, was named the new head coach of the Orlando Magic on Thursday.

Donovan, who was believed to be the top candidate for the Kentucky University opening, will take over for Brian Hill. He’ll be the eighth coach in the franchise’s history, but the sixth since 1997-98 ( the previous five in order: Chuck Daly, Doc Rivers, Johnny Davis, Chris Jent and Brian Hill).

Iavaroni gets his first shot

The Memphis Grizzlies officially announced on Thursday that have named Marc Iavaroni as the team’s new head coach.

This will be Iavaroni’s first head coaching job in the NBA. He has been an assistant under Mike D’Antoni the past five seasons with the Phoenix Suns. The last three and a half years he has been the team's lead assistant.

Kerr stepping into the front office?

Also, on Thursday the Associated Press was reporting that the Suns were close to naming Steve Kerr as the team’s new general manager. Kerr, who is currently an analyst for TNT, was drafted by the Suns in 1988. He played for six different NBA teams in his career from the 1988-89 season to 2002-03.

He would reportedly replace Mike D'Antoni, who held the titles of general manager and head coach. D’Antoni took over the title of general manager when Bryan Colangelo left to become the general manager of the Toronto Raptors.
