I would have to think that Les Koenning would be one of the coaches who recruited him since he is the OC, coaches QB's, and since Newton was at a Texas JUCO at the time, and that was his territory.
The other I'm not sure who it would be, but if I had to take a wild guess, it would be Hevesey because he was at Florida with Cam.
My second guess would be Tony Hughes because he is the recruiting coordinator.
