Bro, I respectfully disagree.
JA has already proven himself and gets the benefit of the doubt when he plays a game that he struggles in. Every QB has games where they look average or stink up the joint.
If he struggles, he’s still one of the top QBs right now. If he plays well, it just reveals what we already know about him.
JA’s next hurdle is to play well in the playoffs. Those are the games that are now career defining for him.
