It's that time of year. San Antonio, counted out as a championship contender, gets serious. Right now, they are the sixth seed in the West, safely in the playoffs, having won 12 of their last 16. They could move up. They're a half-game out of fifth and two and a half out of fourth. Just to prove what they're capable of, they beat the NBA-leading Cavaliers 102-97 in Cleveland Friday night, led by Manu Ginobili's 30 points, then beat the Celtics 94-73 in Boston Sunday night, led by Ginobili's 28. Ginobili, hurt much of last year, has been taking up a big share of the scoring load lately with Tony Parker out. Ginobili has averaged 24.2 points in the 12 games since TP went down.
