Perhaps the problem is Justin.
His stats were not very good last year.
Regardless of how fast he is, dude was way over matched play after play.
Not sure what his sack percentage was last year, because I just couldn't take watching the ineptitude.
Perhaps next year, fields will be better.
Also, in my own personal opinion, Young QB's need a run game, even in an alternate reality.
Reality is, I can't offer you much help, I just got here.
