Don't know. Some of that depends on what you want in a QB. My uneducated opinion is he would definitely rank behind Pickett and Willis based on upside. He's probably in the range of Ridder, Coral, and Howell, but I personally like Howell and Ridder more than Jones. To me Jones' ceiling is mid-range starter and his floor is low end starter. To me, that's not good enough to win in the NFL and I'd rather take a chance on a guy like Pickett, Willis, Ridder, Coral, or Howell who I think have much higher ceilings. But, I will say that all except for Pickett probably have much lower floors than Jones.
But, I'm no professional so take it for what it's worth which isn't much.
