I agree with Henry, defense could use more fresh blood the next couple years. The coaches can keep talking all they want, I'm still looking forward to seeing the O-Line play. If the line is not improved, it not only could be the reason for Plan B, but also can take away many options next offseason.
To be honest, since you always need camp arms I don't mind drafting QB's late and having UDFA's come in every year. You have to play the lottery to win it. Look at Blanchard, honestly the staff (and Matt mentioned it himself) probally never thought he would have stuck around to make training camp.
I don't consider Cutler elite, not so far anyways, but he is a great starter. That is better than most teams have, and I can't wait to see the recieving core in action this year. Balancing out the run game should boost this offense.
