For coaches you have to split pro and college
Lombardi-- name on the trophy, nuff said
Brown--- so many titles and the father of the modern passing game
Shula-- perfect season, most wins
Landry--- The only guy who was innovative on both sides of the ball. Invented the 4-3, was using multiple shift offense and the shotgun 20 years before everyone else. 20 straight winning seasons in a sport where the average career is 3 or 4 years.
I know Bay area people are screaming for Walsh, but he was a Paul Brown disciple.
College--- Crgildart nailed it Paterno belongs on Dante's list and no other
Leaving off some great coaches even with that list Osbourn, Bo, Woody, Switzer
And Artis Gilmore instead of the over rated Rodman
