Alex Smith may be the favorite for the job, but 49ers coach Jim Harbaugh says rookie quarterback Colin Kaepernick will have a chance to win the team's starting job. "We're evaluating it daily and, really, it's a mindset of letting the guys compete for it," Harbaugh said after the team's preseason opener. "There hasn't been an opportunity so far to be a clear-cut, definitive winner in the quarterback competition. We just forge ahead."
