Who would be on your Mt. Rushmore of head coaches? 

Lombardi, Walsh, Gibbs, Landry, Shula, Reid, Belichick, Grant, Halas, Coryell, Parcells?

I'd omit Coryell (never won the SB, not as good an overall regular- or post-season record as others on your list, winning 57% of all games and going 3 -9 in the playoffs, making the playoffs in 6 of 13 years as HC) and add:

• Chuck Knoll - 4 SB wins, playoffs in 13 of 21 seasons, 10-4 in playoffs vs 3-6 for Coryell, 57% overall- and 67% playoff winning percentages, though his overall winning % did tail off considerably and the Steelers missed the playoffs in his last 3 seasons as HC, 
  

and maybe 

• Madden - 1 SB win, won 75% of regular season games and 56% of post-season games in 10 years, made the playoffs in 8 of his 10 years as HC, &/or
  
• Dungey - also 1 SB win,  won 67% of regular season games and 47% of post-season games in 13 years, playoffs in 11 of his 13 HC years.
  

Also instead/ahead of Coryell, I'd consider:

• Hank Stram - 1 AFL chamionship with KC pre AFL/NFL merger + won 1 post- merger SB, 58% of his regular season games and 63% of post-season games in 17 years. His downsides were making the playoffs in just 4 of his 11 post-merger years as HC, and finishing his career with two forgettable seasons with New Orleans, going 7-21, &
  
• Ditka - won 1 SB,  and 56% of regular season games and 50% of post-season games in 14 years as HC, making the playoffs in 7 of those 14 seasons. As with Stram, a downside was finishing his his career in <drum-roll, please>, New Orleans, where his record was 15-33 over 3 seasons with no playoff appearances.
  

Main takeaway for these last two - New Orleans, where coaching careers go to die.....
