In five of the 49ers' six games this season, Kaepernick has rushed for fewer than 23 yards. In his last four games, he's averaged 15.8 yards, and he's had 172 yards this season. That's nine fewer than he had in last season's division-playoff win against the Packers, which helped inspire an avalanche of how-will-defenses-stop-the-read-option stories in the offseason.
