Ethical?

[J.Albers]

We have a local coach who runs a play he calls 'DIMEOUT', where he tells the officials before the game that to be aware of it, and that it is not a time out. A player calls it and three offensive players walk toward the bench, with the player inbounding the ball and another offensive player remaining on the playing area. The opposing players all tend to walk toward
their bench, leaving the goal totally unprotected for an easy basket.

Although there is nothing in the rules about this type of situation, it borders on unethical or unsportsmanlike, as it is designed to intentionally deceive an opponent, thus gaining an advantage. The opposing coaches usually express their displeasure, sometimes rather vocally.

Sounds like Bush league to me. Any comments?
