A weekly examination of the San Francisco 49ers' quarterback play.Rewind: Colin Kaepernick had a strong bounce-back game in Week 4 in a 35-11 win at St. Louis last Thursday night. In Weeks 2 and 3, Kaepernick struggled and the San Francisco offense combined for 10 points in two defeats. Kaepernick's numbers against the Rams weren't overwhelming -- he was 15-of-23 for 167 yards and two touchdowns -- but the 49ers had success on the ground, and Kaepernick made plays when needed.
