That's a problem the NBA created by having way too many games. These sports seasons are a fucking brutal toll on the human body, no matter how in shape these people are. The NBA has an 82 game season, all just so they can get a bigger TV deal and sell more tickets, merchandise, fucking soda. Out of those 82 games, teams have to face each other three or four times a season for no reason whatsoever. If you were a championship caliber team, would you be risking your best players against the championship level teams, who you're sometimes only playing twice a season, or are you going to rest them against the more bearable teams, which you play more against and have more games with, which means you rack up more wins and get a higher seeding come playoff time?
Not to mention, the NBA nor the fans really care about these players, they just want to see the best play against the best. Which is understandable, but also why they should just do home and away games for the regular season. Until then, the NBA should be the ones punished, not the teams, because that will trickle down and punish the players.
Even the playoffs are ridiculous. A best of seven series? There's no point, other than to churn out more content for TV.
