Considering these turbulent times, the Nets’ Christmas wishes surely revolve around family and faith, goodwill and world peace and such. But truth be told, somewhere on that holiday wish list is a little bit of a hot streak. “I’d love to see us continue to improve,” coach Kenny Atkinson said. “I thought last year we did that after the All-Star break. I thought we really improved. Can we — after this little Christmas break we have — can we continue to improve?” The Nets have lost four of five going into Tuesday’s game in San Antonio, but their last two showed a clear improvement over their season-high four-game skid. After their most-lopsided victory of the year, blowing out Washington on Friday, they largely outplayed the Pacers on the road before finally falling in overtime Saturday. The Nets chartered home Saturday night, spending the holidays with their families. They haven’t played on Christmas Day since 2013 — one of the precious few upsides of struggling the past few seasons — but they’re hoping to come out of this mini-break showing some signs of an upward trajectory. Atkinson would love to get D’Angelo Russell healthy, Jahlil Okafor in shape and Allen Crabbe shooting well again. But most of all, he would just like to see growth as a team.
