Goff is no dummy, at least according to the Wonderlic test. Average test score for QB is 25.9
Goff - 36
Garoppolo - 29
Wilson - 28
Murray - 20
The thing is he probably was the brightest bulb in the room. Weinke was being a jerk, way to build a relationship with your QB. Another brilliant choice of a coach in the Fisher era.
I lived in Charlotte at the time when Weinke was QB. He led the Panthers to 17 consecutive losses as their starting QB. Career QB rating of 67, 15 TD, 26 INT.
Speed would still probably chose him over Goff if he was still playing
Sincerely ..... Mrs. Goff
