If Bryant McKinnie doesn't get suspended (in criticisms of Brad Childress's conservative playcalling, few point out that the Vikes are without their starting left tackle--would they take more risks in the passing game if they could rely on their pass protection?), if Madieu Williams doesn't get injured (the Vikings lost two close games in which they gave up some key long passes over the middle; does that happen if they aren't starting a rookie safety?), if Heath Farwell doesn't get injured (he is a special teams captain and a good cover man on kick returns; did his absence play any role in Green Bay's punt return for a touchdown?), is this happening? Regardless of whether or not Tarvaris Jackson is capable of starting at quarterback right now (and I'm now in the "he's not" camp), there are other facts outside of Jackson's control that result in the team being 0-2 right now.
