The Los Angeles Clippers have not formally requested permission to interview Celtics coach Doc Rivers in the wake of widespread reports about Rivers' potential departure from Boston, but there is strong mutual interest between the parties, according to sources close to the situation.

Sources told ESPN.com on Thursday that Rivers is highly intrigued by the idea of coaching the Clippers in the event that he and the Celtics part company after nine seasons together and one championship in 2008. Sources say the Clippers, meanwhile, would immediately vault Rivers to the top of their list if he became available as they continue a coaching search that, to this point, has focused on Brian Shaw, Byron Scott and Lionel Hollins. The Clippers brought in Hollins for a second straight day of interviews Friday, coaching sources told ESPN.

The Los Angeles Times, citing several NBA executives, reported Wednesday that if Rivers decides he doesn't want to coach in Boston anymore, the Clippers would be interested in him and he would become their No. 1 choice.

ESPN.com has also learned the Celtics and Clippers -- in an offshoot of February's Kevin Garnett-to-L.A. trade talks -- discussed expanded trade scenarios that could have sent both Garnett and close friend Paul Pierce to the Clippers before the league's Feb. 21 trade deadline.

Sources say those talks, before breaking down, were centered on Boston getting back both prized Clippers guard Eric Bledsoe and young center DeAndre Jordan and did not involve Clippers star forward Blake Griffin.

It is not yet known whether the Clippers intend to revive those trade discussions and pursue either Garnett or Pierce -- or both -- in conjunction with this month's NBA draft. But one source familiar with the Clippers' thinking told ESPN.com the club plans to be "very aggressive" and "shake every tree" in terms of upgrading the roster this offseason. Acquiring Garnett or Pierce -- or both -- would make Rivers even more of a natural coaching target for the Clippers.

In the February trade talks between the two clubs, the Celtics also were trying to send Jason Terry to the Clippers, but the Clippers did not want to take back the two years and $11 million that remain on Terry's contract.
