Byrds INT stats tell an interesting story. Especially how different his '09 season was vs '10-'12.
My argument is that '09 is an anomaly and his 3-5 INTs per season are a truer gauge. Also interesting, Byrd doesn't have interceptions vs "elite" QBs or even "Top 10" qbs (unless you're considering M. Schaub) Here are all of the QBs Byrd has intercepted in his career, sometimes multiple times. It's a who's-who of back-ups.
Delhomme
D.Anderson
Sanchez
V. Young
Cassel
Tannehill
Tebow
Beck
Skelton
Kolb
Henne
Schaub
