Mavericks at Rockets7 p.m. Friday, Toyota Center, Houston TV: FSSW Radio: ESPN/103.3 FM; KFLC/1270 (Sp.) Records: Mavs 1-0, Rockets 1-0 About the Mavericks: What an impressive debut by the Mavericks’ three new starters in Wednesday’s 118-109 season-opening win over Atlanta. Monta Ellis had 32 points, eight assists and two steals; Jose Calderon had 11 assists, and Samuel Dalembert added nine rebounds. Add that to what the Mavericks’ 35-something crew did — Dirk Nowitzki (24 points, five assists), Vince Carter (21 points) and Shawn Marion (12 points, eight rebounds) — and it was a banner night. About the Rockets: If anyone needed to be reminded who is the game’s most dominant center, Dwight Howard issued that reminder Wednesday when he scored 17 points, grabbed 26 rebounds and blocked two shots as the Rockets defeated Charlotte Bobcats 96-83. James Harden scored 21 points, and center Omer Asik added 14 rebounds. Reserves Francisco Garcia had 19 points and Jeremy Lin added 16. Howard and Asik could give the Mavericks major problems inside.
