I am interested in him as well. He floudered in Greenbay where Mccarthy is a QB guru. They liked him enough to try and hide him on their practice squad. They even matched the Bills Offer. That says something at least. He's got the arm and Size to be a NFL QB. If he can't grasp the mental part which he reportedly had issues with then he will be a journeyman QB.
The Bills seem impressed with him but that doesn't say much given their track record with QB's. Holcomb, JP, Trent, Fitz have all been terrible.
