Aside from a costly interception by QB Colin Kaepernick that set up a New Orleans' touchdown, it's hard to blame the Niners' offense for the team's latest first half deficit. The Saints lead 31-20 at the half in large part because the Niners still can't stop anyone. They moved coordinator Jim O'Neil to the booth to call the plays but that hasn't helped. The Saints have 146 rushing yards already against San Francisco's 32nd-ranked run defense and the 49ers gave up a 75-yard touchdown run to Mark Ingram, who was untouched on the play. The offense, meanwhile, had its best half of the season with 319 yards.
