8:25pm: ESPN.com's Marc Stein reports that the Nuggets are now receiving strong consideration from Miller's camp along with Oklahoma City and Memphis.
5:36pm: Mark Berman of Fox 26 tweets that NBA sources have confirmed the Rockets' reported offer to Miller.
3:28pm: The Rockets have formally extended an offer, Stein tweets. Houston has the $2.652MM room exception available. Meanwhile, Marc Gasol has joined the Grizzlies contingent trying to persuade Miller to go to Memphis.
1:59pm: The Thunder have spent the past couple of days as the apparent leaders in the race to sign Mike Miller, but Chris Tomasson of Fox Sports Florida tweets that they have company. The Grizzlies, along with the Thunder, are the front-runners, though Miller is still evaluating his options, Tomasson says. Marc Stein of ESPN.com hears the Nuggets are a threat as well, with plenty of playing time to offer following the departures of Andre Iguodala and Corey Brewer this summer (Twitter link).
The Spurs, Rockets and Warriors were also linked to Miller when he cleared amnesty waivers this week, but it's not clear whether those teams remain in the mix. The Cavs strongly considered claiming Miller while he was still on waivers, but they haven't been mentioned as a candidate to sign him outright. A report surfaced this week that Miller was considering fusion surgery on his back, which was giving pause to teams with thoughts of claiming him off waivers, according to Adrian Wojnarowski of Yahoo! Sports. Luke Adams of Hoops Rumors speculated that the surgery news was leaked to dissuade the Cavs from claiming him, pointing out that Miller "made it clear to people around him" that he didn't want to play in Cleveland, as Jason Lloyd of the Akron Beacon Journal tweeted.
The Thunder appear unwilling to go into luxury tax territory to bring Miller aboard, but they're reportedly willing to waive DeAndre Liggins or Daniel Orton to accomodate a minimum-salary contract for Miller. That may not be enough to corral the sharpshooter, as the Nuggets can use the bi-annual exception to sign him, and the Grizzlies have the bi-annual as well as the mid-level exception. The Thunder have both of those exceptions available, too, but using either of them would push the team above the $71.748MM tax threshold.
The 33-year-old Miller, coming off a pair of championships with the Heat, isn't ready to retire any time soon, saying last month that he felt he could play for four or five more years. He might not be ready to accept a minimum-salary deal, even though he'll still be getting the remaining $12.8MM from his contract with the Heat.
