Best NFC South QB? By one measure, it's Ryan

Posted by ESPN.com's Pat Yasinskas

When people talk about quarterbacks, they often turn to winning percentage as the bottom line.

If you subscribe to that theory, you might be a little surprised. New Orleans' Drew Brees is widely recognized as the best quarterback in the division, but not if you go purely by this formula. Brees has a 55-51 record and a .519 career winning percentage. That places him fifth among NFC South quarterbacks with at least 10 career starts.

Atlanta's Matt Ryan is No. 1 after going 11-5 (.688) as a rookie last season. Carolina's Jake Delhomme is second. He's 50-31 (.617). Tampa Bay's Byron Leftwich is third with a 24-22 record (.522). New Orleans backup Mark Brunell is fourth with a 78-72 record and a .520 percentage.

Atlanta's Chris Redman and Carolina Josh McCown are the only two other division quarterbacks with 10 career starts. Redman is 4-6. McCown is 12-19.
