I have yet to meet a head coach who wants to deal with a quarterback controversy. Coaches, as a rule, like certainty and stability. Quarterback controversies by definition lead to the opposite. They create distractions when you're seeking focus, and they can spark division when you're searching for togetherness.
Colin Kaepernick was brilliant on Monday night in leading San Francisco to a 32-7 beatdown of the Chicago Bears, firmly placing the 49ers atop the short list of NFC favorites at 7-2-1. In the process, Kaepernick also microwaved a full serving of quarterback controversy that San Francisco head coach Jim Harbaugh will be dealing with, more than likely, for the rest of the season.
That's the thing about controversies -- they're not easily controlled or contained.
Controversies are living, breathing, sentient things that set their own agenda, and the circumstances in San Francisco are fertile breeding ground for such things.
