I can see the ones who have crazy innovative offenses that will turn a team around over night ala Andy Reid, McVey and Shanahan. They would be worth the risk but a lot of these so called offensive geniuses ain't nearly on the level of those 3. I read Lions and Texans fans saying they cant wait till Johnson and Slowick are gone next season because how shaky the offenses can be. Trust, neither is going to any team and turning an offense around unless they have hella hella weapons and a QB. It'll be just like the Arthur Smith hire in Atlanta.
