49ers, Gore trying to build running game back up after slow start this season

Wearing a gray San Francisco 49ers hoodie, soft-spoken running back Frank Gore walked around team headquarters with a familiar smile and strut Thursday.

Gore is in good spirits again, and so are the 49ers (2-2) entering Sunday night's game against the Houston Texans (2-2) at Candlestick Park. Gore gashed St. Louis for 153 yards on 20 carries in San Francisco's 35-11 rout of the Rams last week to snap a two-game losing skid and a rare running funk.

Gore says the 49ers "got back to being us."

Perhaps no player has contributed to San Francisco's success more than Gore the past three seasons. Since 2011, San Francisco is 9-0 when Gore runs for at least 100 yards.
