Jarren Williams is a wonderful gifted quarterback that just doesnt have it between the ears. He needs perfect situations to shine and absolutely implodes when things don't go as planned. He can move and shuffle but he's not working out a solution because he doesn't have the bandwidth.
Too many receivers left open under pressure, too many forced passes to first options because of tunnel vision.
He's physically talented, smart etc. But if he doesn't have the balls to keep it together and to make something happen when it falls apart.... All that means nothing.
