The National Football League is a quarterback-driven league. While the offensive supporting cast, defense and even special teams may be just as important to an NFL team's success, strong quarterback play is typically a staple of Super Bowl champions and contenders.
Quarterbacks are always in the spotlight, even in the offseason. Aaron Rodgers, Joe Flacco and Tony Romo have all made headlines this offseason for signing massive contract extensions. So have the New York Jets, Buffalo Bills and Philadelphia Eagles, who are all carrying two-way starting quarterback competitions into their respective training camps.
Some quarterbacks have continued their way up the league's quarterback hierarchy, while other quarterbacks are just trying to prove themselves as viable starters for their team in 2013 and beyond.
In the following slides, we'll take a brief look at each team's starting quarterback situation, counting down from No. 32 to No. 1 in the fashion of Ron Jaworski's annual quarterback countdown featured on ESPN.
Teams with open quarterback competitions are listed only once with multiple quarterbacks discussed.
