This schedule isn't really any more compacted than prior years, it was just a very compacted off season and was made worse with some postponements, but the actual season length is in line with prior seasons. 72 games in one week shy of 5 months vs. 82 games in one week shy of 6 months is like 0.8 games more per month this year, which isn't exactly much different. And before the 17-18 season it was more like 5.5 months which would put the games this year at about even.
I'd also like to point out that Wilt Chamberlain played 82 games and 48.5 mpg (missing less than 50 minutes all year) in a season that started on October 19th and ended on March 14th (so basically shorter than this 72 game season). That season the Warriors even played on 5 consecutive nights as well as 4 consecutive nights, and had a bunch of 3 straight nights, including a 6 game in 7 day stretch. And because they didn't have an all star break, the game was January 16th, Wilt played even more. So Wilt played on the 13th and 14th, all star game on the 16th, and then played on the 17th, 18th, 19th, 20th, and 21st. So Wilt basically played 6 straight nights and 8 games in 9 days, without missing a single minute (well maybe in the all star game he missed some). The Warriors played back to back games in the playoffs and even with travel in each of their two playoff series. Again, Wilt missed less than 50 minutes that entire season. And it isn't like they were flying on comfy private planes for the travel.
