No no my friend
The fact that three coordinators got fired tells you that there were more problems than just one unit. There are holes all over this team, including the defense. There are also a lack of quality player problems and a lack of good coaching problems starting with the head coach
As I've had time to reflect on it I do think that this move could work because these are guys that Matt is comfortable with and the offense in TB under Dirk was top 3 last yr. So it should work...but we've gotta commit to a legit run game and we need at least 3 starting OL for Dirk and his down the field passing attack scheme to have success
