Every team in the NFC West has been starting a quarterback drafted since 2010 in recent weeks.
The trend will likely continue unless Kevin Kolb returns from injury and gets the start for Arizona against Seattle.
I've put together a chart showing 2012 stats for all quarterbacks drafted since 2010 (minimum 10 attempts). They're ranked by Total QBR, which is a rate stat, not a cumulative stat. The order doesn't necessarily reflect how much each player has contributed to his team over the full season. It does generally reflect how well each quarterback has played when given a chance.
