DALLAS — The Portland Trail Blazers must feel like they are in an NBA time warp. First they got beaten by Jason Kidd, now Kidd and Peja Stojakovic.Even the Dallas Mavericks are feeling the retro mood. They’re up 2-0 in a playoff series for the first time since 2006.Stojakovic tied his career playoff best with five 3-pointers and had 21 points, and Kidd continued his surprising scoring surge with 18 points, powering the Mavericks to a 101-89 victory on Tuesday night in Game 2 of their first-round series.Dirk Nowitzki led Dallas with 33 points, but was practically a complementary player. He was at his best after the 30-something, former All-Stars built the lead, scoring 14 points in the fourth quarter — including the team’s final 11 — to help the Mavericks keep the Trail Blazers from ever making a serious push. He scored 18 in the fourth quarter of Game 1.“We’re never sure which two or three guys we’re going to get hot, but we need contributions from a lot of different guys to be successful and that’s what we got tonight,” Dallas coach Rick Carlisle said.Portland had a lot of things go right, from LaMarcus Aldridge scoring 24 to Gerald Wallace and Wesley Matthews regaining their scoring touch after struggling in the opener. But the Trail Blazers got only 11 points from their bench, none in the second half. And while they were limiting Nowitzki to 5 of 15 shooting through three quarters, former All-Stars Kidd and Stojakovic were lighting them up.
