It's a highly competitive market with plenty of NBA teams searching for head coaches right now.

And the Milwaukee Bucks jumped into the deep end of the pool on Wednesday as they elected not to retain interim coach Jim Boylan and immediately began a search for a successor.

Former Miami Heat and Orlando Magic coach Stan Van Gundy and current Houston Rockets assistant Kelvin Sampson are considered serious candidates for the Bucks position, held for four-plus years by Scott Skiles and for the last 54 games by Boylan.

Boylan went just 22-32 (including playoffs) after taking over for Skiles in early January, and the Bucks were swept out of a first-round Eastern Conference series by the defending league champion Heat.

Other teams are searching for a coach, too, including Charlotte, Detroit, Philadelphia and Phoenix. Cleveland moved quickly and hired Mike Brown for a second stint as Cavaliers coach.

And several current playoff teams could be changing coaches in the off-season.

So what exactly are the Bucks looking for in their next coach? The chosen one will be the 13th in franchise history and the 11th under current owner Herb Kohl.

"I think in this day and age, it seems like you need the coach who can show the player that he cares and then coach the heck out of him after that," Bucks general manager John Hammond said.

Hammond said he had no set timetable to make a decision.

"What we want to do is get it right rather than limit ourselves on the kind of person we're going to hire," he said.

"Guys are different today. To just walk in and throw down the hammer, it seems like it's a different day and age. Guys are searching for that (communication). But at the end of the day, there still has to be discipline and you still have to coach them."

Van Gundy compiled a 579-371 record in seven-plus seasons with Miami and Orlando and he led the Magic to the 2009 NBA Finals. The 53-year-old did not coach last season after being let go by Orlando, where he endured the Dwight Howard saga during the 2011-'12 season.

The 57-year-old Sampson served as an assistant with the Bucks for three seasons under Skiles before joining Kevin McHale in Houston, where Sampson is the associate head coach. The Charlotte Bobcats have asked for permission to interview Sampson, a North Carolina native, when the Rockets are ousted from the playoffs.

Houston played at Oklahoma City in Game 5 of the teams' Western Conference playoff series Wednesday night.

The Bucks took a chance on Sampson after he left Indiana University under the cloud of an NCAA recruiting scandal. He knows the Bucks organization well and forged a strong relationship with point guard Brandon Jennings, who is a restricted free agent this summer.

Hammond said he believes the Bucks have enough roster assets to attract a strong candidate.

"This thing surely is not broke right now if you look at some of the young pieces we have, especially up front," Hammond said. "You've got a real nice, intriguing young piece in Larry Sanders.
