Coaching Rumors: Karl, JVG, Clips, Hollins, Nets

After we heard yesterday that there are some question marks surrounding George Karl's future in Denver, TNT's David Aldridge echoes that report, writing that the head coach is "antsy" about his current situation. According to Aldridge, the Nuggets don't plan to exercise the 2014/15 option on Karl's contract, which means he'll be on an expiring contract in '13/14.

"They want to play it out and see where they're at," one league source tells Aldridge. "And they're not going to budge on that."

As Aldridge notes, the Nuggets don't appear to actively be seeking a replacement for Karl, but if he wants to leave for a more lucrative opportunity when his current deal runs out, the team may not be inclined to stop him.

Here are a few more of the latest coaching-related rumblings from around the league:

• Jeff Van Gundy and the Clippers talked multiple times about the team's head coaching job, but discussions are now dormant, reports Adrian Wojnarowski of Yahoo! Sports. Van Gundy was reportedly at or near the top of L.A.'s wish list, but it doesn't sound as if he's a serious candidate at this point.
• Two of the Nets' top coaching targets may become available for interviews within the next few days, as Tim Bontemps of the New York Post writes, pointing to Lionel Hollins and Brian Shaw. In fact, according to ESPN.com's Marc Stein (via Twitter), the Nets formally requested permission today to interview Hollins.
• The newly-retired Jason Kidd has interest in coaching, tweets Stefan Bondy of the New York Daily News.
• Vitaly Potapenko, who was a Cavaliers lottery pick way back in 1996, will return to Cleveland as an assistant coach to Mike Brown, tweets Wojnarowski.
