It is not hyperbole to suggest that a narrative surrounding a quarterback has never shifted as violently and quickly as it did for J.J. McCarthy during the fourth quarter of his NFL debut on Monday night. For three quarters the Michigan product, playing his first game after missing the entirety of last season with an injury, was quite pedestrian and looked a long way off from being the franchise's answer at quarterback.
Then he looked poised and polished as Minnesota put 21 unanswered points up to secure a 27-24 as McCarthy proved capable through the air and with tough running. Now the overreaction machine is swinging in the other direction.
