Why wouldn't he put up big numbers in a power offense? he has tons of agility but most of it used close to the line of scrimmage since they go 4 wide and the receivers rarely hold the blocks long enough, he has to make tons of people miss. Not to mention half the time he gets the ball at an angle so he doesn't have much momentum going. Put him in an i formation he is going down hill, can use his agility more in the open field, plus there would be more carries. The offense could be featured around him, he could have a similar season to Matt Forte. I mean I wouldn't mind them keeping the system, but with more pistol, same principles as the I but you can keep 4 wide and more variety in the playcalling in the run game. Half of his carries are draws, they mostly use more of a pistol look in the redzone. The playcalling for the run game has been predictable based on where Line is lining up.
I don't think anybody else runs the run and shoot besides SMU and Hawaii. The best thing to do would be to promote someone from within, which there is talks of on the message boards (not sure of the name), but people say he isn't qualified having only been a positions coach, but there have been several coaches that have been hired as head coaches with only experience as a position coach. I would hate to see a zone read type coach come in and use Line as the dive back.
