In extrapolating Kaepernick's 10 starts (including the playoffs) over a 16-game season, one number in particular leaps out: 803. That's how many rushing yards he was on pace to gain over a full season. Since 1950, four quarterbacks have rushed for over 800 yards in a season: Michael Vick (he did it twice), Bobby Douglass, Randall Cunningham and Robert Griffin III.
