I think he will be very average. I don't think he will be bad, but I don't think he'll be good.
I think he's a smart guy. Reminds me a bit of Pete Carroll in his early days. I don't think he's been around the college game for too long to not be able to make some adjustments. But, I question his transition from an offensive schematic standpoint. I think the read-option will be in for a rude awakening in the next 2 years, but I also think he's too smart and good to not put forth some good gameplans and that's enough to make a serviceable team.
The problem for him is that he comes into the NFC East, the toughest division in football.
