On his second of 12 assists of the night, Rajon Rondo  became the 101st player in NBA history to amass 4,000 assists and just the sixth player in the storied history of the Celtics  to reach the plateau. Bill Russell  is next with 4,100. Bob Cousy  is the all-time franchise leader with 6,945.
But that milestone was just one significant milestone for Rondo Sunday in a 102-91 loss to the Mavericks at TD Garden.
“It’s definitely an honor, especially to have so many in this organization,” Rondo said. “It’s right up there. It’s definitely an honor to get that many assists. I’ve played with a lot of great players. Give them credit. They have to make the basket.”
The Celtics  point guard played a season-high 36 minutes and looked good doing so.
“I played 36 tonight and I’m a little sore but I’ll be fine,” Rondo said. “I try to listen to my body as much as possible.”
Celtics coach Brad Stevens  said after the game that he spoke with Rondo and believes the time restrictions are all but gone after his return from ACL surgery.
‘Time limit’s off, yeah,” Stevens said after the game. “Not playing in the back-to-back. Probably will be cleared to play in back-to-backs again very soon. I asked the question right after we met prior to the game and it sounds like, again, that’s sooner rather than later but no time issues.’
Rondo clarified that position when he spoke post-game, about 45 minutes after Stevens made his initial proclamation.
“I wouldn’t say [limit] is completely off. I won’t be playing 40. When I’m out there and my adrenaline is going, I’m fine,” Rondo said.
Rondo will not be playing in Milwaukee on Monday night. Rondo would not say whether he would travel with the team or not on Sunday.
