Just saw a stat about how Michael Jordan had 11 seasons of over 80 games played.
And he was playing closer to 40mpg too. It's really amazing how much the games played has changed over the years. Stars played more minutes and more often, and major injuries were a lot rarer. Look at the Celtics players:
1980, Celtics had 3 play 82, 5 play 80+, 7 play 73+
1981, Celtics had 6 play 82, 8 play 80+
1982, Celtics had 2 play 82, 4 play 80+, 7 play 76+
1983, Celtics had 2 play 82, 3 play 80+, 8 play 72+
1984, Celtics had 1 play 82, 4 play 80+, 8 play 71+
1985, Celtics had 0 play 82, 2 play 80+, 7 play 75+
1986, Celtics had 2 play 82, 5 play 80+, 8 play 77+
1987, Celtics had 0 play 82, 1 play 80+, 8 play 71+
1988, Celtics had 0 play 82, 1 play 80+, 7 play 70+
1989, Celtics had 1 play 82, 3 play 80+, 6 play 72+
The whole rotation is available over 90% of time. And that was the era of when they played some back-to-back-to-back games, 4-games-in-5-nights (I even saw a 5-games-in-6-nights/8-games-in-10-nights stretch), flew commercial (sleeping in airports and sitting in coach), stayed in cheaper hotels, sneaker technology/comfort was non-existent, training/nutrition was in the dark ages, etc.
Compared to now:
2022, Celtics had 0 play 82, 0 play 80+, 4 play 71+
2023, Celtics had 1 play 82, 2 play 80+, 4 play 74+
You're lucky to get a couple of role players available for most of your games.
Or look at All-NBA, this is the average games played for the 1st and 2nd team over the years
1980 - 80.5
1990 - 78.8
2000 - 75.4
2010 - 77.9
2019 - 72.5
2023 - 66.1
