Kap's inaccuracy as a drop back passer had been an issue all season. He had done a decent job covering up that flaw by making big plays with his legs. In the NFL though you eventually have to drop back and throw accurate passes in tight windows. There wasn;t a single time this season where Kap threw a fade pass into the endzone that resulted in a TD. Not even once.
There is a reason so called running qbs rarely win the Superbowl. If Kaep can't develop into a better drop back passer then were in big trouble.
