"I'm not allowed to talk about [negotiations] but all I can tell you is he's one of a bunch of guys who came in, they all got together and said 'Let's go down to the practice facility and start working out together,'" Cuban said. "So they're down there now and so that's exciting to see, and he's part of that group."
Noel hasn't play for the Mavericks long but he became a solid contributor in his 22 games with Dallas, averaging 8.5 points and 6.8 rebounds a game, starting 12.
The front office wants him back, coach Rick Carlisle noting in April that Noel is "a guy that we've got to get signed."
Noel said at the time that it's "probably the biggest offseason of my career."
He also expressed an affinity for the team and city.
"I love Dallas," Noel said April 13. "In my short time here, I've really enjoyed it. With the pieces that we have, and the opportunities we'll be seeing in the near future, I think there's a lot to be excited for."
Cuban seems to think so too, viewing the informal workouts at the Mavericks facility this week a step in the right direction.
