The OKC Thunder have stiff competition this summer for Mike Miller’s services — the Memphis Grizzlies, Houston Rockets and Denver Nuggets are all making a hard push to land the sharp shooter. Per ESPN: “Miller, according to sources, met face-to-face Friday with new Grizzlies owner Robert Pera and CEO Jason Levien after an earlier sitdown with Thunder general manager Sam Presti. Sources said that Thunder All-Star Kevin Durant and Grizzlies All-Star Marc Gasol have both taken an active role in recruiting Miller, who has received interest from a number of contenders after being released earlier this week by the Miami Heat via the amnesty provision. The Nuggets have joined the hunt, sources said, with the promise of minutes at the wing positions after losing two key performers in that department — Andre Iguodala and Corey Brewer — in free agency. Most of the teams pursuing Miller are offering a minimum salary but pitching the opportunity to take on a prominent role as a perimeter specialist on a championship contender. The Houston Rockets, sources said, have also made Miller an offer that the 33-year-old is considering. [...] Earlier this week, Miller said he was feeling healthy and looking forward to next season, telling the South Florida Sun-Sentinel: ‘I’m excited about the next spot. I’m re-energized. I really am. I’m just feeling healthy. I’m ready to play. I started to get back in [the gym] again last week and I can’t wait to play again next year.’”
