Down 2-0 in the Western Conference semifinals with San Antonio, the Trail Blazers don’t have much time to figure out the Spurs with the series moving to Portland tonight at the Moda Center ( 7:30 p.m., ESPN). Only 16 teams have come back from a 2-0 deficit to win a playoff series, most recently Memphis against the Clippers last season. The only time Portland has rebounded after a two-loss series start was the in 1977 finals against Philadelphia, which remains the team’s lone NBA championship. The teams split the regular-season series 2-2, but San Antonio has dominated this series. On Thursday night, the Spurs built a 20-point lead and won 114-97. – AP
