A lesson Tennessee Titans fans could potentially learn this season is that sometimes a coach just makes a better head coach than a defensive coordinator, like Matt LaFleur in Green Bay.
Another great example of this is Mike Vrabel who was bad as a defensive coordinator, but who looks to be a solid leader and CEO of a team. Well, at least before today.
After the Titans let Tyrone McKenzie walk and go to the Detroit Lions it raised eyebrows because he was on the assumed short list for the DC job. I think everyone assumed at this point that the DC job was going to go to Shane Bowen the Titans OLB coach.
