I do, however my main focus isn't because I believe he's terrible.
First off, I would like to see him get an opportunity. If Dave Culley earned one...then so has Daboll IMO. While I believe that Daboll falls into the same category of Nate Hackett and Leftwich (OCs that look way better because they work with a top NFL QB) he is very well liked by his players and could do some good things in the right situation.
Second, I'm not sure how much more Josh can learn from him. Maybe a new OC has lessons that Daboll does not have and it would add more to Allen's growth and the growth of others in the offense.
