Haven't eaten pork, but haven't seen a pig run? He's not the kind of person who can only be managed, but can't manage others.
Larry Bird clearly knows that for an NBA team, when a coach is managing players, the ones that need the most attention are often those on the bench.
Because players who can become starters on an NBA team are often very responsible and train very hard, the coach doesn't need to worry too much about them in this regard.
And those sitting on the bench, especially the ones at the end, their morale and mindset often determine the team's atmosphere.
This is the bucket effect in team management. If the players at the end of the bench are energetic, train hard, and are always ready to play, then your team will definitely have no problem.
Besides the players at the end of the bench, you also need to pay attention to the unruly players, of which there are many in the NBA.
