QB Watch: 49ers' Colin Kaepernick

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.

Fast-forward: Kaepernick and the 49ers play against Houston at home on Sunday night. The Texans are somewhat vulnerable against the pass. That means the key for the 49ers will be their offensive line, which played at a high level in St. Louis after slumping the previous two weeks. Houston’s J.J. Watt and Brian Cushing cannot take over. If they do, Kaepernick may be uncomfortable all game.

Third-down success: The 49ers are hoping Kaepernick can stay hot on third downs. In St. Louis, Kaepernick throttled the Rams on the key down. He was 7-of-10 for 98 yards and both of his touchdown tosses were delivered on third downs.

Prediction: Kaepernick will be better at home in this game than he was in a Week 3 loss to the Colts. While his receivers are still an issue, I think Kaepernick gets the job done. I see him going 21-of-32 for 276 yards and two touchdown passes.
