Teams mull if backup QBs have what it takes to start (The Associated Press)

Matt Hasselbeck is one of the poster boys for success when it comes to backup quarterbacks changing teams and becoming effective starters in the NFL. After throwing just 29 passes in his first three seasons as Brett Favre’s backup in Green Bay, Hasselbeck spent most of the next 10 years as the starter in Seattle where he made six trips to the playoffs, one Super Bowl and three Pro Bowls. For every successful example like Hasselbeck or Mark Brunell, there are probably even more busts such as Brock Osweiler, Kevin Kolb and Matt Flynn.
