Video: Challenging convention on QBs

A relatively low confidence rating for the San Francisco 49ers' backup quarterback situation seemed strange amid the team's understandable excitement for 2011 second-round draft choice Colin Kaepernick.

Why would a promising prospect such as Kaepernick inspire less confidence as a backup than a journeyman with dimmer long-term prospects? That's the question I considered in the latest "Blogger Blitz" video above.

Kyle Kaepernick, brother of Colin, offered thoughts on the subject with a couple tweets earlier Tuesday. Thank you for the mental jump-start, Kyle.
