NFL teams are always looking for the next star quarterback. Since 1998, 12 of the 15 number one overall picks in the NFL Draft have been quarterbacks. They often become the face of a franchise and are thought to be the most important position on the field by many.
However, picking a quarterback is an inexact science. For every Peyton Manning (Indianapolis' No. 1 pick in 1998), there is a JaMarcus Russell (Oakland's No. 1 pick in 2007, who no longer plays in the NFL). Perhaps the perfect example of this is the Houston Texans.
In their first season as an expansion franchise, Houston selected David Carr out of Fresno State with the No. 1 overall pick, hoping that he would lead Houston's new franchise to greatness while keeping the team stable under center.
However, the Carr pick never worked out. The Texans toiled in mediocrity for years before they discovered that they didn't need the No. 1 overall pick to land their franchise quarterback. Matt Schaub, a talented passer who received little attention out of college (he was drafted by the Falcons in the third round), was sitting on the bench behind superstar Michael Vick for the Falcons.
Not every backup quarterback-turned-starter story is a success, but there are many diamonds in the rough that go undiscovered. Ahead is a list of five current backup quarterbacks who I believe can be starters in the NFL.
