Basketball is a team sport. We all know this, of course, and yet sometimes we attribute team results to one player, or we hold every player equally responsible for the team’s results. In a good season, that’s how you get misconceptions like “[this player] won the championship for the team.” In a bad season, that’s how you get misplaced complaints like “[the team’s best player] doesn’t want to win” or “everyone on the team stinks.”
None are accurate, of course, but the line of thinking required to end up at these beliefs has been common orthodoxy among basketball fans for generations, and sometimes it takes those beliefs to be challenged for the consensus to shift.
