Different Starting QBs by Season

There's a distinction the Cardinals will be looking to avoid in 2013.
The chart from ESPN Stats & Information shows 47 starters used across the NFL last season. That was down from the previous two seasons.
Pittsburgh (three) and Arizona were the only teams to use more than two last season. Ten teams used two.
Seattle's Russell Wilson and Arizona's Ryan Lindley were among eight rookies to start in 2012, matching the record for most in a non-strike season since the 1970 merger. There were eight in 2010 as well. The previous high, seven, was set in 2004 and 1977.
Rookies combined to post a 46-43 record as starters last season, doubling the previous post-merger record for victorious starts by rookies. The previous post-merger highs for rookie victories were in 2011 (23-38), 2008 (22-10), 2004 (18-14) and 2006 (17-25).
