Either your math is wrong or you had a typo. Kaepernick is only 6:1 in the past 5 games. 6 TDs in 5 games isn't great.And there's Cowboys fan logic for you. The 49ers have had their top 2 receivers from last year out for the entire season so far, yet they're finding ways to win big. Kaepernick is playing great right now (well I guess only if 9:1 TD:Int in the past 5 games is good), especially considering the WR circumstances.
Oh I just noticed he had 3 rushing TDs so I guess that is how you got your 9. You generally don't included rushing TDs when talking about TDs and Ints. If you do, then you should also include his 2 fumbles that he lost during the 5 games.
