Here's the current/active coaches with 9 wins/season and at least 50 wins, to give a sense of sustainable success: Defense: Belichick, Tomlin, Carroll, Rivera, Mike Smith Offense: Reid, McCarthy, Payton ST: John Harbaugh Just missed: Pagano (D), Zimmer, (D), Arians (O), Garrett (O), Caldwell (O), Jim Harbaugh (O) Your list presented in anotherway: Defense: Brady, Roethlisberger, Wilson, Newton, Ryan Offense: McNabb, Rodgers, Brees ST: Flacco Just Missed: Luck, Bridgewater/Bradford/Keenum, Warner/Palmer, Romo/Prescott, Stafford, Smith/Kaepernick So it's a QB list as much as a coaching list. I am asking myself now, who are the top QB's that aren't on this list? The 50 win threshold & active status eliminates quite a few: E. Manning, Rivers, Carr, Cousins I'm sure the credit goes to coaches and QBs both and in some cases other ways to build a team (elite running/defense teams), but we all know its a QB league. Nothing shocking there, but I think it's clear that Mitch needs someone doing a great job developing him, even if it's not necessarily the HC. Historically, it's pretty interesting defensive vs. offensive coaches. Shula, Landry, Noll, Parcells were defensive guys Gibbs, Reeves, Shottenheimer, Levy, Shanahan were offensive guys. A quick glimpse looks pretty close to 50/50 offensive/defensive coaches in the top 20 all-time wins (with guys like Halas, Paul Brown, Lambeau, etc. who did it all back in the day in their early 20s).....though I don't know if all them averaged 9 wins per year (for example Coughlin's at 8.5 for his career, and 8.5 for the Giants and Jags each ironically). And John Harbaugh worked as a defensive coach before become a STC, so he'd make it 6-3 in favor of defensive coaches. But I think the trend is clearly going offensive coaches way. Sean McDermott won 9 his 1st year this year. Anthony Lynn won 9 his 1st year this year. Marrone has an 8.3 win average and has won 9 games in 2 of his 3 seasons (1-1 interim in between) Gase won 10 his 1st year and only year with his starting QB healthy. (still average of 8 per season) McVay 11 in 1st year this year. Pederson averaging 10 wins in 2 years Koetter had a 9 win season his 1st year last year. Kyle Shanahan may never lose another game apparently. I think there's a good chance that at least 3 of these guys get there. McVay and Pederson are ahead of the curve and have young rosters under contract for the foreseeable future. McDermott looks like a damn good coach considering his GM tried to tank the season and rebuild and he still made the playoffs. On the defensive side, it looks like a case of teams just not really going after defensive guys as much because of the league being so QB driven, but it looks like only Zimmer and Quinn will get there. Of course, there are only 2 other defensive minded coaches that currently have jobs that were hired in the last 4 years (others being Bowles and Vance Joseph). I think Bowles is a really good coach, and he won 10 his first year but a pair of 5-win seasons since which were probably overachieving, but still puts him at risk of getting 9 per and 50 total anytime soon.
