There have already been 511 different men who have acted as the head coach for an NFL team for at least one game. If we restrict that to 14 games, we cut that number to 373 men. Using Vince Lombardi’s fist season as a start point (1959), we cut that number down to 275. Of those 275 only 93 have or had an overall winning record (some are still coaching). Of those 93, fifteen are in the Hall of Fame as coaches (and another four are in the Hall as players).
| Head Coach | Overall Win% | Number of HC gigs |
| John Madden | 76% | 1 |
| George Allen | 71% | 2 |
| Don Shula | 68% | 2 |
| Tony Dungy | 67% | 2 |
| Bill Cowher | 62% | 1 |
| Bud Grant | 62% | 1 |
| Joe Gibbs | 62% | 2 (same team) |
| Bill Walsh | 61% | 1 |
| Ton Landry | 61% | 1 |
| Al Davis | 59% | 1 |
| Bill Parcells | 57% | 4 |
| Chuck Noll | 57% | 1 |
| Marv Levy | 56% | 2 |
| Mike Ditka* | 56% | 2 |
| Joe Schmidt* | 56% | 1 |
| Jimmy Johnson | 56% | 2 |
| Raymond Berry* | 55% | 2 |
| Tom Flores | 53% | 2 |
| Art Shell* | 52% | 2 (same team) |

So it’s common, even among Hall of Fame coaches, to get more than one turn on the carousel (even if it is with the same team like Joe Gibbs and Art Shell).
