This is not a bad idea. I'm not sold on the "knows how to develop a QB part" - his QBs in Miami were nothing special and Romo was already pretty developed coming into this season.
However, Garrett did go to Princeton and Columbia, so I'd imagine he knows something about being an athlete in a strenuous academic institution. [sarcasm] Do we really want some ivory tower carpetbagger coach for our team? When I think Atlanta, I think antebellum South [/sarcasm]
