i think the best historical comparison for marleau is dean prentice.
when prentice retired, he'd played an amazing 22 seasons. he didn't break any records, because there was gordie howe. but here was the top five in games played in 1974, as of prentice's last game:
1. gordie howe - 1,687 games, 25 seasons
2. alex delvecchio - 1,550 games, 22 seasons and bits of two others
3. tim horton - 1,445 games, 22 seasons and bits of two others
4. harry howell - 1,411 games, 21 seasons but was a little healthier than prentice
5. dean prentice - 1,378 games, 22 seasons
6. ron stewart - 1,353 games, 21 seasons
7. norm ullman - 1,330 games, 21 seasons
8. red kelly - 1,316 games, 20 seasons
other than ullman, those guys were all retired. the next two guys were also active, bucyk in 9th and doug mohns, who was a year away from retiring but hung on to just pass prentice for 4th, in 10th. ullman also only played one more year and also passed prentice, bumping him to 7th. bucyk bumped him to 8th a year after that. in 1979 mikita would bump prentice to 9th.
but here's my point: prentice wasn't bumped to 10th until 1992, when larry robinson passed him. that top ten of howe, delvecchio, bucyk, horton, howell, ullman, mikita, mohns, prentice, stewart stayed intact for a long time, more than a decade.
(it wasn't until 1998 that mike gartner, larry murphy, and gretzky all hit the top ten at the same time, pushing mohns, robinson, and prentice out. messier and bourque joined them a year later, and before you knew it it's the lockout and prentice is tied for 26th with vinnie damphousse.)
but dean prentice never made the hall of fame. for along time he was pretty high on the hall of very good list, but the committee never relented on him the way they eventually did on dave andreychuk. and prentice had some high moments: he was a second team all-star in 1960, at LW behind bobby hull. he was a stalwart on the rangers' big first line with andy bathgate and larry popein. he finished top ten in goals twice, peaking at 4th in 1960, when he also finished 10th in points. he finished 8th in assists in 1962.
he didn't win any cups but made the finals in 1966 with the red wings, reunited with bathgate as now secondary players behind gordie howe and norm ullman.
this is basically patrick marleau's career, no?
another interesting note: horton, howell, prentice, and stewart were all rookies in 1953.
in 1998, marleau (5th), thornton (9th), chara (15th), and matt cullen (20th) were all rookies. in the same way that prentice's incredible longevity looks not quite so good when you had three other guys he was rookies with him all in the same ballpark, including two hall of famers, it's the same with marleau alongside his contemporaries, two of whom are also still active, incidentally. marleau has more games than them, because he was incredibly durable, but he hasn't outlasted them, yet anyway. they all are at the exact same 22 years as prentice.
