A good, or even brilliant, coordinator does not necessarily a good head coach make. It certainly merits an interview, if for no other reason than to pick the coordinator's brain, ask what scheme or personnel changes he would make with the Dolphins, etc. But an X and O's genius with no leadership ability and management skills can only lead to disaster. That's why I don't really care whether the new HC comes from the offensive or defensive side of the ball. I'm more concerned about his overall plan for the team, game management and leadership abilities. Remember, Billick got his shot as an offensive genius, and never presided over a good offense in Baltimore (though he did win with that stout defense and seemed to have good game management before losing the team in 2007). Unless Carmichael Jr. comes with Brees, we can't predict the offensive success will follow.
Let's face it, now that we are out of the market for a big name, known entity at head coach, we have no choice but to trust in Ross and Ireland (and Peterson -- or was he involved in Fisher only? -- still confused) doing the interviews and research the right way and discerning which man has the right head and heart for this job. And yes, I just threw up in my mouth a little as I typed that.
