If a coach has been restricted to the dugout, what may he still do?

When a coach is restricted to the dugout, their ability to interact with the game is limited. However, being involved in a charged conference at the dugout area is permissible. This allows the coach to communicate with players and strategize without leaving the confines of the dugout, adhering to the restrictions placed upon them. This option ensures that the coach can still participate in team discussions and make crucial tactical decisions while remaining compliant with the rules governing their restricted status.

The other options are not allowed under the restrictions. Calling for a timeout from the field, interfering with plays, or assisting players while plays are ongoing would be violations of the coaching limitations and could lead to further penalties or sanctions against the coach or team.
