I'll say this in defense of Bill Walsh over say Chuck Knoll, if you look at Knoll's record outside that decade period where Bradshaw & Co. were killing it (i.e. 1972-82), it's not overly impressive.
1972-1982 is one more year than Bill Walsh was a NFL head coach.
Outside of coaches like Joe Gibbs and George Halas, most great coaches had a single great QB that won the overwhelming majority of their championships.
Walsh had Montana, Belichick had Brady, Paul Brown had Otto Graham, Landry had Staubach, Lombardi had Starr. Don Shula won all of his with Bob Griese.
It was a remarkably lousy list, prone to pick more modern folks with shorter, high W-L% careers..
Seriously. Is Jimmy Johnson that much better than Buddy Parker?
Arguably, the three best runs in history are Browns from 1950-1955, Lombardis from 1960-1967, and Noll's from 1974-1979. Walsh doesn't have anything to compare.
Deal is, if you go back to 2004 or so, where ESPN had people vote for the best coaches of all time, Bill Walsh was the highest vote getter in the NFL. I think *that's* why he ended up #2 on this list.http://sports.espn.go.com/espn/espn25/s ... estcoaches
I will note some inconsistency on ESPN's part, wrt coaches..http://espn.go.com/page2/s/list/topcoaches/010518.html
Paul B gets shafted for reasons not relating to his ability to coach. He won so much in his early career he became set in his ways. He became out of step with the times. He tended to be tight fisted and didn't forgive or forget. Paul is probably the reason Mac Speedie isn't in the Hall of Fame. But you have to ask yourself, if best coach a popularity contest? Or is it not?
For me, there are 4-5 coaches you could reasonably claim are BOAT, and those are Lombardi, Brown, Halas, Shula, and maybe Curly Lambeau. Everyone else is just merely great.
This is way off topic, but that list gets my goat..
