Bill Russell, Kendrick Perkins react to Jaylen Brown’s record night on Twitter

The Boston luminaries were rightfully impressed by the ascending superstar’s historic performance against the Cleveland Cavaliers Sunday.

It’s getting pretty hard not to notice the Boston Celtics may have more than one superstar on their roster, and among Celtics alumni, several notable figures are already taking note of the rise of fifth year wing Jaylen Brown.

On Friday night, the Georgia native tied a career-high 42 points in a losing effort against their Atlantic Division rival, the Philadelphia 76ers. On Sunday, Brown followed up his virtuoso performance — unfruitful though it may have been in securing the win through no fault of his own, despite his postgame comments — with yet another game for the record books.

That last contest caught the eye of Celtic icon and fellow civil rights activist Bill Russell, who made a point of shouting out Brown on Twitter after the game.

The legendary Bostonian big man wrote “Great playing tonight
[Jaylen] keep it going,” to which Brown replied, “Yessir!” with a green heart emoji after it.

It also got the attention of champion Celtic center Kendrick Perkins, who tweeted “Can you say Most Improved Player and first time All-Star!!!” in response to the historic performance.

We certainly can — and it isn’t the first time Brown has been mentioned in that conversation.

If the Cal-Berkeley product keeps it up, All-NBA is absolutely in the question as well.
