Job of Head Coach: Motivate, Discipline, Monitor - let players and coaches know what they are doing good and bad. Be where the Buck Stops -- stand in front of the media on the good and bad days. In the unique case of head coach of the Dallas Cowboys -- the most important job is to not take any of the credit or limelight from Jerry Jones when the Cowboys do good. Also to be the "end" to coaches differences.
Job of Coordinators: Watch film and setup game plans to match your teams strengths to their teams weaknesses. Make sure the position coaches are teaching correct form and technique. Making sure that you have the correct groups working in synch....ie you don't want DL shooting the same gaps that LBs are blitzing. Build terminology, playbooks, and make sure everyone is on same page. These guys should be able to know strengths and weaknesses of both their own team, and be able to watch film and "write the book" on how to attach the other teams weaknesses. Guys who are great strategist, are not always great motivators and disciplinarians.
Job of Position Coaches: Teach correct form and technique. Great teachers aren't necessarily great strategist nor great motivators/leaders. Al Harris is a very good teacher, but I have no clue if he is a strategist or motivator/disciplinarian.
IMO, Head Coach is pretty simple to find. Find a leader of men who is a great motivator and disciplinarian. Honestly that seems like Vrabel to me. I think Mike Irvin would make a great HC as well.
Excellent coordinators would be harder to find, IMO. There are some very good coordinators out there, but most are wanting to be paid, so they want to be the next failing HC (always about the Benjamins).
Give me: (and YES I know the Jerry Jones would never be comfortable with this or do it)
Mike Vrabel as HC.. disciplinarian and has been there done that.
Robert Saleh as DC.... reminds me of young Wade Phillips.......excellent coordinator and motivator, but will probably never be a great HC.
Kurt Warner as OC...... he understands the game and what it takes. This one would be fun.
..... pay these men a good base pay and X amount per WIN. Then let them get the position coaches they need. Hold all accountable, but let them be the highest paid IF they win the Superbowl. There is no salary cap on coaching presently. Stop the being the best marketed team and become the best FOOTBALL team. No clue if Vrabel, Saleh, and Warner could work together, but if they could.......WOW
