3:21pm: The Bobcats have also requested permission to interview Rockets assistant Kelvin Sampson, according to Jonathan Feigen of the Houston Chronicle. Sampson's Rockets remain active in the postseason, though the team is one loss away from elimination.
2:19pm: According to Adrian Wojnarowski of Yahoo! Sports (Twitter link), Pistons GM Joe Dumars met with McMillan last week. Ownership is expected to be involved in today's formal interview, says Wojnarowski.
1:02pm: While the Cavaliers struck quickly to fill their head coaching opening, two other Eastern Conference lottery teams appear to be moving at a more deliberate pace. The Pistons have begun to interview candidates, according to Vincent Goodwill of the Detroit News, who tweets that Lindsey Hunter interviewed with the team yesterday, while Nate McMillan will do so today.
McMillan and Hunter appear to be the early favorites for the Pistons' coaching job, but they're unlikely to be the only candidates interviewed by the club. With 14 teams still alive in the postseason, teams searching for a new head coach may have to wait until later in the spring to seek permission to interview assistants on those playoff clubs.
Meanwhile, the Bobcats have asked for the Cavaliers' permission to talk to assistant coach Nate Tibbetts, according to the Cleveland Plain Dealer (Twitter link). If that story sounds familiar, it may be because the Bobcats interviewed the Cavs assistant a year ago, before eventually hiring Mike Dunlap.
The Bobcats seem to be revisiting a number of past candidates, having also been linked this month to Pacers assistant Brian Shaw and former Lakers assistant Quin Snyder, both of whom were interviewed by Charlotte last spring.
