Nets get harsh lesson from Jayson Tatum, Jaylen Brown in blowout loss to Celtics

This time, the Nets had to face Jaylen Brown.And a fully engaged salty Boston team. The result of this rematch was predictable, the Nets suffering a 139-114 loss at the hands of the reigning champions before a sellout crowd of 18,112 at Barclays Center. After blowing a fourth-quarter lead last Friday in TD Garden — falling in overtime to the Brown-less Celtics — Wednesday was no heartbreaker.

And right now he is checking the best player every single time.It doesn’t matter if it’s Luka Doncic.

He wants to take the challenge.And, I mean, it’s good to see,” said Dennis Schroder, who spent 2021-22 in Boston.

“They’re competitive over there.And I mean, the last one, last season in the playoffs was incredible.” The Nets saw their league-leading 3-point defense shredded, and have now dropped three of their...
