Allen is a much better quarterback than Jackson. I live outside Baltimore and Jackson is very limited in the passing game and has issues holding onto the ball. CLE shut down the run game in the 2nd half of the season finale and SD shut it down for the entire playoff game. D-coordinators will have all offseason to stop the run, so if Jackson cannot expand the passing game beyond hitting TEs down the seam, he may be Tim Tebow 2.0.
I would put 8 in the box, take away the short middle in the passing game and force Jackson to throw deep outs and down the field because I don’t think he can do it. Their receiving core will be one of the weaker units in the league which will not help things.
