It is a team game, your arguing a hypothetical over a fact -
If stars aren't adjusting and playing hard defensively - then the team can't adjust. Coach can't adjust if the pieces on the floor aren't playing both sides of the ball - he can tell them and show them video but if they choose not to - his only option is to bench them ~ which isn't going to happen - they are being paid too much.
How do you not understand his logic? Fact 2 guys that are paid millions, and in the PAST been top players in the league are - having trouble playing defense and rebounding and supporting their teammates.
