Coaching lifer Larry Brown, known for rebuilding franchises and moving to the next challenge, resigned from his job with Philadelphia Monday.

His departure means that almost one-fourth of the NBA's 29 head-coaching jobs now are vacant. Within the week, the Washington Wizards are expected to fire Doug Collins, and then there would be eight available.

The league is set for one crazy summer of turnover, and in the process, even Orlando might feel the effects.

Speculation again has Magic Coach Doc Rivers as a candidate for a new job. The Houston Chronicle reported Monday that the Rockets, searching for a successor to Rudy Tomjanovich, might call Rivers. The Rockets are first expected to flirt with veteran candidates Mike Dunleavy, Jeff Van Gundy and Brown, but if those attempts fail, they would be interested in Rivers, a young, rising coach.
