I don't necessarily think the Hooker pick means the end of Goff, it could just be a matter of them feeling that they were in position to take a flyer on him just in case something happens to Goff whether it be injury or ineffectiveness. If Goff continues to excel then worst case scenario is you used a 3rd RD pick on a backup QB, a position that you were prepared to make a "strong offer" to fill anyway.
