Quick Take: 49ers 31, Lions 13

Posted by ESPN.com's Mike Sando

The 49ers performed as expected in all areas against one of the worst teams in the league.

Few storylines were more predictable in Week 3.

The Lions replaced offensive coordinator Mike Martz after last season because they wanted a coordinator with a stronger commitment to the running game. Which meant Martz was going to pound away against the Lions' overmatched defense, proving he'll run the ball when he has a top back and a lead to protect.

Frank Gore's 27-carry, 130-yard performance helped the 49ers build a 25-14 lead in first downs. Gore also helped Martz answer questions about pass protection after Seattle sacked J.T. O'Sullivan eight times in Week 2. The Lions sacked O'Sullivan just once, for 1 yard, and the quarterback rushed for 32 yards on eight carries.

We have seen this before from Martz. The Lions were 6-2 and teeming with confidence during his final season in Detroit. They fell apart and missed the playoffs.

The 49ers have little time to celebrate. They head to New Orleans in Week 5 before returning home for games against New England and Philadelphia. Then comes a road game against the Giants and a home game against a Seattle team that could be healthy and vengeful by then.

Martz has given the 49ers hope after a brutal 2007 season. The 49ers have given Martz something he never had in Detroit: a marquee running back.
