I don't get it. Must be an American thing that everything needs to be bigger, more tough.
16 games in January and then 15 games in the short February month.
That's a crazy schedule. Just simply crazy.
Most sports (including basketball) in the Netherlands/Europe have 2 games a week and often (like football/soccer) players and coaches are complaining about overload. Sure you have less opportunities to make substitutions in football, but still.
Raymond Verheijen graduated in movement sciences, an author on exercise physiology, fitness and football coach, once did an study on rest days in football and he found out that at a minimum players needed 3 full days to recover. When matches were scheduled that didn't meet that requirement it turned out that the team that had more rest had a great advantage in their results leading to competition distortion.
I have no idea if there has been done such a research on basketball, but I can't imagine that a basketball player can fully recover from playing 30+ minutes a game with an average rest of less than 48 hours between games.
