The word “longevity” gets tossed around so much in this thread that it almost seems like a dirty word.
“Sustained excellence” is how most of us quite rightly contextualize it.
Here’s a simple example. We know that Howe broke Richard’s all-time record for goals early in his 18th NHL season (1963-64).
How did he perform in the 5 year period immediately before achieving this milestone (58-59 through 62-63, his 13th-17th seasons) and then in the 5 year period immediately following the milestone season (64-65 through 68-69, his 19th-23rd seasons)?
From 58-59 through 62-63, Howe played 344 games, missing just 6 over the 5 year period (all in 60-61). He put up 386 points in those 344 games. He finished 4th, 5th, 5th, 3rd and 1st in the regular season points races.
From 64-65 through 68-69, Howe played even more games, 359, missing just 1 regular season game in the 66-67 season. He put up 401 points in those 359 games. He finished 3rd, 5th, 4th, 3rd and 3rd in the regular season points races — in his 19th-23rd seasons in the league.
There’s no drop off. Howe achieved just as much in his 19th-23rd seasons as he did in his 13th-17th.
That’s not “longevity” — it’s sustained excellence that boggles the mind, and the figures I’ve provided completely exclude his prime! He’s borderline “Big 4” without those huge years.
