While some posters in this thread have stated that's it's the coaches responsibility to have five players, at least one poster has indicated that it's the team's responsibility. For those who may be confused by this, by rule, not mechanic, it is the team's responsibility, not the coach's, and the technical foul penalty goes to the team.

Penalized if discovered while being violated: A team shall not have more than five team members participating simultaneously. Team technical foul. A team technical foul is charged if recognized by an official before the ball becomes live following the first dead ball. If it was not recognized by either official, but was called to their attention after the ball became live following the first dead ball, it is too late to assess any penalty.

Before some esteemed Forum members get all over me, I am simply clearing up some confusion that may have appeared in this thread, by rule. I am one who believes that, by mechanic, it is the officials responsibility to wait until they are sure that there are five players from each team, before putting the ball in play. Of course, this won't prevent a player from simply running out onto the court during a live ball.
