teams do that because they know the secondary market will do it too.
Teams also do that when other teams show up, regardless of who's on the team. Those trash mid 2010s Lakers still commanded top dollar because their fanbase travels. Same with the Knicks, Celtics to a lesser extent. TV wants those players all night, every night, no matter what. But TV is also be tight if those players are a shell of themselves come playoff time. There was that first Warriors title run where they got the Finals and it seemed like every team along the way had players who couldn't play. The Finals where everyone but LeBron seemingly was hurt took a lot of air outta that series. Yes, fans have a right to be bummed out, but hoops fans are wired set everyone up to where no one can be satisfied out of potentially just whoever showed up or watched that particular night's game, which nowadays doesn't benefit the bigger picture.
