USA today ranks NFL Head Coaches
I'd trade Gibbs for Madden and Belichick for Collier on my personal rankings, but its hard to fault your reasoning for your list.
I'd take Gibbs as well. Three SB wins with three different starting Qb's in a nine year stretch.None of those starters will sniff the HOF either.
I'd still put Madden on my list. He's 2nd all time in winning % among coaches with 100 wins or more. Vince Lombardi is the leader and it's not
by much. Lombardi had a .640 winning %. Madden at .631.
Madden also coached in the era of the 72 Dolphins and the 4 time SB champs Pittsburgh Steelers. The latter is considered by many the greatest
team in history. I know it's the what if game,but Madden could easily have 4 rings instead of Noll if fate had been kinder to John.
The only question I have about Bellichick is how will he do once Brady is retired. Noll wasn't the same once Bradshaw retired. George Seiffart
once had the highest winning % ever while he coached SF with Montana and Young as his starting Qb's. He later became a fired HC in Carolina with
Rodney Peete at the helm. I also believe Noll went to his grave regretting not drafting Dan Marino when he had the chance.
