Arkansas did run a whole lot of zone read with Matt Jones. Obviously Nutt has that in his playbook. It would be tough to implement something like that on short notice, but I could see that offense being a good fit for a player like Masoli if Nutt wanted to go back to it.
And by the way, for Goat, why would it be a good idea to blitz the crap out of the Wildcat if the QB running it can throw the football? We didn't use the Wildcat much last year because teams just stacked the box and didn't respect the pass option out of it, so we couldn't run out of it. If we run it with a QB that can throw, whether that's Mackey or Masoli, teams won't be able to stack the box on it.
