"The Warriors welcomed back Andris Biedrins on Monday. Not the tentative, bumbling big man they've seen most of this season, but the productive, energetic big man they remember from years past.Biedrins brought with him his contributions of old in a 114-97 win over the visiting Chicago Bulls at Oracle Arena. He finished (4-for-5 shooting). He rebounded (19). And he defended (a career-high eight blocks)."That's the Andris that we miss right there," guard Monta Ellis said. "We knew eventually he was going to get back to that. His presence - rebounding, blocked shots, everything - we needed that and he gave it. He's the reason we won this game."Of course, the Warriors also had to welcome back Biedrins' cringe-worthy free-throw shooting. He was 1-for-7 from the line, no doubt denting the front rim with a few of his bricks."That free throw doesn't have much chance," coach Don Nelson said. "I know it. You know it. He probably knows it."The Warriors (12-27) snapped their three-game home losing streak largely Biedrens played his best game of the season after missing 35 games because of injury. He followed his first double-double of the season (Friday against Milwaukee) with a season-high 39 minutes and anchored a defense that held Chicago (18-21) to 36.5 percent shooting. The Warriors had a season-high 57 rebounds."
