Gets to sit, sounds right. Bench personnel, not so much. I don't think this is so clear.

Besides the TO question, the AC can't go to the table for a CE? Can't enter the court to prevent a situation from escalating? Can't permit team members to leave the bench area for an authorized reason? Is not responsible for the conduct of bench personnel?

Unless a rule or case says otherwise, isn't it more appropriate to treat the AC as the HC, with the loss of the coaching box?
