No to Caldwell. He hasn't even managed to produce an average ground game or get his RB going. Lions run game has been a joke, and the Ravens groud game in Superbowl season wasn't good either. I'd rather have McCoy who has shown at least some adaptability or Bevell, whom I consider the best offensive mind among them. Had a rough couple years in Seattle with no OL but in general his schemes are well designed. In the end, none of them excites me very much. DeFilippo would be a great hire. Young, flexible, outside the box thinker. That's what we need for a young QB. Hopefully they come up with another name. Morton, recently fired OC of the Jets, got a lot out of his unit with Josh McCown at QB, Roby Anderson as top WR and a bad OL. Great RB production too between Forte, Powell and McGuire. Would be a great hire to use David Johnson's skill the right way!
