Tramaine Brock is kicking himself for not having a third interception. He came oh so close. "I wanted it," he said. The San Francisco 49ers turned a prime-time showdown into an all-out pick party at The Stick. Brock perfectly read Matt Schaub's first pass of the night, jumped in front for an interception and ran 18 yards for a touchdown just 90 seconds into the game, setting the tone for a stellar defensive performance in a 34-3 victory over the Houston Texans on Sunday night.
