Keep in mind Pre 1977 the NFL played seasons of 14 and 12 games and had less playoff teams hence less playoff games.
Landry would be well over 300.
Hats off to the great Andy Reid nonetheless.
The NFL started in 1932 and until 1947 varied from 10-12 games and then from 47-60 12 games; 60-78 14 games; 78-2021 16 games and 17 since 2021
So bluntly speaking George Halas would have a LOT more wins looking at it that way. Probably near 400.
Tom would not have gotten all that many more regular season games but probably another 10-15.
BUT playoffs would have been a fair number more for him and of course Halas and other older coaches.
So this particular stat needs an asterisk
