What does it mean to go home fishing after losing the basketball game?

Fishing usually refers to players who are not qualified to participate in the playoffs or have been eliminated in the playoffs before the arrival of the playoffs. The time is usually May or later. At this time, the United States is in the long summer solar terms, and people's leisure cannot be separated from seaside activities such as fishing and yachting.

So fishing is to tease the team or players that the season has ended ahead of schedule and there is no chance to win the championship, so we can only wait for the new season.
