Actually, while I agree that CSP is known as a "pass happy" coach, I think it is really a misnomer.....he is more of a situational match up type coach....I can list multiple years where your premise regarding the run/pass ratio is demonstrably false (below are full seasons, not a game or 2).....
2006 run pass was 45-55
2009 45-55
2017 45-55
2018 48-52
2019 42-58
2020 49-51
And, not coincidentally, those were some of the Saints best years, I think CSP was always striving for balance....you can argue that he often abandoned the run too soon some years but to call him "pass happy" is not accurate....IMO
