Top 4 NFL Head Coaches of the Super Bowl Era (not necessarily in order)
Bill Belichick
The resumé is undeniable. Namely 9 Conference Championships and 6 Super Bowl rings... both are the most ever. His knowledge of the game and his awareness from the sideline are impressive. His two greatest achievements as a head coach are SB 36 and SB 53. The obvious knock on Belichick is his lack of success as a head coach without Brady. The SB 52 debacle is his low point. Belichick will likely catch Shula for all-time combined wins but I he may not catch Shula in regular season wins. But he will surpass Dan Reeves in regular season losses.
Joe Gibbs
Gibbs has the greatest accomplishment of any head coach in the history of the NFL: 3 Super Bowl championships with 3 different starting quarterbacks (none hall of famers and two were pretty much garbage). He has a slightly better postseason winning percentage than Belichick. And he has the highest postseason winning percentage of all head coaches with 15 or more games.
Don Shula
His resumé is also undeniable. All-time leader in wins, both regular season and combined. He's 4th all-time in losses but he has at least 78 more wins than the 3 head coaches with more losses. Of course he's got the only undefeated season in the history of the league. And the back-to-back Super Bowl championships. My big knock on Shula is he never won a Super Bowl with Dan Marino who was an absolute phenom of his era.
Bill Parcells
Parcells is a polarizing figure but there isn't a head coach that I admire more than Parcells. He turned four different franchises into winners and postseason contenders, which is a phenomenal achievement. He won 2 Super Bowls with 2 different quarterbacks. Regarding his time in New England, he rejuvenated fan interest and took over a team that had pathetically struggled under Rod Rust and **** MacPherson. He made the team relevant again and brought them to a Super Bowl but couldn't overcome an incompetent quarterback performance.
Honorable Mentions: Chuck Noll, Bill Walsh and Tom Landry
