Jeff Fisher stands out
The best available coach for any opening is Jeff Fisher. You could throw Bill Cowher and Jon Gruden into the discussion, but it's doubtful that either would leave his comfortable broadcasting existence at this point.
Fisher, on the other hand, is very interested in coaching again. He has a 140-126 record as a head coach, and he has been to a Super Bowl. His teams in Houston and Tennessee were consistently competitive.
Fisher has the kind of leadership qualities that make him a CEO-style coach. He has the credibility to sell his program to his team and to his fan base. His experience makes him stand out above almost all other available and interested candidates.
All about connections
Coaching searches in the NFL usually come down to who you know.
Ireland is working hard to maintain personnel power, and presently has owner Steve Ross' trust. Fisher's presence wouldn't threaten that, and his coaching skills could help Miami's underachieving team blossom.
Pioli needs a coach who can maximize quarterback Matt Cassel's skills, and who better than the person who helped Cassel blossom at New England.
Billick, Fisher best bets
If the Dolphins are smart, they hire Brian Billick as their next head coach. Billick wasn't perfect in Baltimore, but he had bad luck. If Jamal Lewis doesn't blow out his knee and Kyle Boller doesn't spend several years tripping over his shoelaces, Billick would still be coaching in Charm City. The man understands organization and he knows how to motivate.
