Kyrie Irving's 30 points help the Celtics push the winning streak to 15. Brad Stevens, dissatisfied in the best of times, had the next shot of the winning streak that the Celtics brought to Philips Arena last night. We have not played well enough to consider this winning streak to be valid in my opinion. We have discovered ways to win games. We have to play a lot better. Meanwhile, they seem to have mastered the task of finding ways to win when it seems unlikely. The Celtics have returned 18 points down twice and down 17 points once during a winning streak that reached 15 in a row in a 110-99 victory over the Hawks. And with this victory, the Stevens team added to overcome a 16-point deficit, which is the first quarter hole they climbed against Atlanta. Jaylen Brown, mourning the loss of his best friend Trevin Steede, followed a 22-point performance against Golden State with 27 points against Atlanta in 10 of 13 shots. The Celtics forward, who left before the locker room opened after the victory, continues to amaze with his ability to lock himself in despite the tragedy. He is not alone. That's spirit in the truest form and he understands that, said Kyrie Irving. As I said the other night, the physical presence of your best friend is lost, but your energy still exists. He is still playing with incredible verve. He is perfecting his craft and he is doing it at a very high level. All season Jaylen has been doing many incredible things. He has a lot of strength. Marcus Smart, who once lost his older brother Lawrence for cancer, also understands the need to move forward.
