Jaylen Brown hasn't shared 'frustrations' with Celtics, says president Brad Stevens: 'Nothing but positive'

McGrady, a longtime mentor of Brown's, speculated on Monday's podcast that the All-Star forward may feel underappreciated given how he led the Celtics to the No. 2 seed despite Jayson Tatum missing most of the season while recovering from a torn Achilles.

"I think his frustration lies deeply within the organization and other things that we don't really have the details to," McGrady said. "It's just been a lot of stuff that I've been hearing just going on with the Boston organization with JB. I think part of him is like, 'I showed you guys more of who I am as a basketball player. Not only just, you know, what I did on the basketball court, but the leadership that I displayed within this team, and you've seen that not having our best player in [Tatum].' So, all that stuff, I think just came into play with him and his frustration."

Brown has not made any public comments to that effect, but Stevens reiterated that if there are any lingering issues, he's always open to talking.

"If anybody ever wants to come in and talk about it, and talk about their team, their place, whatever the case may be, I'm all ears," Stevens said. "And that would be 1 through 16 (on the roster), not just Jaylen, not just Jayson, not just the guys that have been here. I think it's really important to be available. So I certainly am, and none of that (frustration from Brown) has been expressed to me."
