Yea this fact has me concerned as well. However, if you were asked right now, would you trade a coordinator for a top 5 ranking the following year? Assuming our D is middle of the pack vs the run and top 5 vs the pass, then I’d expect this team to at least make it to the conference championship game. Would u trade an OC for a conference champ game the following year ? Regardless, It’s not a given that he’d leave if he had success, look at Detroit’s OC, he turned down head coaching opportunities.
