Payton could learn from Coach O’s example

Saints offense was 9th in total yardage and 3rd in scoring, in a year where we played 5-3/4 games with a back up QB and most of the season with our star RB hobbled by a leg injury, and by all accounts.... no viable weapon at #2 WR.

So the knock on SP is likely very situational. In the long run, his offense is borderline elite. You can break it down to some specific situations where it didn't work so well, but I think you'll find that is the case with every football team, past, present, and future.
No one is denying Coach Payton's regular season excellence, he can call it up with the best of them in the regular season.

The issue comes up in the post-season where you go against the Best Defensive minds, with elite personnel and everything ramps up from a physicality, and intensity stand point. You meet the Mike Zimmer's and the Wade Phillips type of Defensive coaches who know all your playcalling tendencies, and tend to exploit them.

As an Offense you have to be able to make adjustments, expect unexpected Defensive coverages, and rush packages, and come out with out of the box playcalls that break tendencies and catch Defenses off guard and that just hasn't happened the past 3 playoff exits, The Offense has come out stale and uninspired the last two playoff losses, and even failed to capitalize off of early turnovers that put them in the opposing Red zone in the 1st quarter in both games. Zimmer has gotten this Offense twice, and Wade once in a span of three pretty disappointing play-off exits.
