who's the best head coad coach in the nfl ?

Its probably what your favorite team is which mine is the bengals and i think the best head coach is Marvin Lewis

There are a number of them. Every single one is good at something. You have Joe Gibbs and Bill Parcells who have been there for so long and know the dizzle. Bill Belichick won enough Super Bowls in a short stint to prove himself. Marvin Lewis is a heck of a mentor. Dick vermeil will surely be missed. Dennis Green is a well known mentor and a great @ss coach who is just in a wrong team, but watch out for his Cardinals this year. Brian Billick is someone who knows the game and he's one the brightest coaches, but he needs stop being lenient on his boys.

Lovee Smith/ Chicago Bears

Ladies and Gentlemen, Bill B-Chick has two sets of plays in the Hall of Fame Gallery...he shut out Peyton Manning a weak after losing his number 2 CB in that AFC game...he won all those games in a row...and lets not forget he helped out Parcells. You will also notice that everyone else this season will be copying his use of the 3-4 defense...yes EVERYONE. So C'mawwn.

A lot of coaches are good. I would give the edge to Joe Gibbs of the Redskins and Mike Shanahan of the Broncos.

Andy Reid

I hate the Patriots, but Belichick has probably the best program in the NFL today.
