I think it's worth it for the league to consider that the modern game has changed when thinking about this stuff. There are more possessions and guys are doing way more than in the past. The human body is only able to handle so many miles, so if players are logging more miles per game, then they are not going to be able to play as many games. On top of that they are competing against the most athletic players there have ever been, so there is just much more wear and tear that has to be considered.
The league is also the deepest its ever been as well. Maybe another way to handle this is minute restrictions on regular season games. Everyone would hate that, but it would allow for more even competition, while preserving health, and since counting stats continue to be important for some reason would give everyone a more level playing field for awards.
I honestly think 40 minute games > 48 minute games due to the time box, but I think the players (well LeBron at least) have already came out against that and prefer less games instead.
