Andris Biedrins is not your typical macho jock, tending instead to be hypersensitive and quick to lose confidence.

His efforts to overcome his self-doubt reached a critical juncture Wednesday when his sinking career hit a new low: He did not start at center for a Warriors team that doesn't have another center on its roster.

"Maybe I was expecting bigger results from myself," Biedrins said, reflecting on his season. "I think that kind of got to me a little bit, and it just kept building and building.

"I don't understand why I'm not at the same level I was before. I think I'm just getting too tough on myself. ... You expect that you'll go out and get 11 (points) and 11 (rebounds) every night. When you don't, you start wondering, 'What's wrong with me?' "

If Biedrins misses a shot in the opening minutes of a regular-season game, he feels like he let his teammates down in the final seconds of a championship game. He sometimes perceives coaches' criticisms of his play as attacks on his character.

Biedrins' emotions played out on the NBA stage last season, when he shot 16 percent from the free-throw line. He was self-conscious about clanging and airmailing foul shots and further embarrassed by coach Don Nelson's suggestion that he try underhanded attempts. So Biedrins went into a shell and was scared to touch the ball on offense.
