Team Responsibility

[Just Curious]

In our adult rec. league, most of the teams have player/coaches, player/managers, or player/captains... Most likely a typical scenario.
When benches act up in the youth rec. leagues, Jr. Highs, or Sr. Highs, the head coach is the one penalized for bench misbehavior.
How have you guys/gals handled (control) bench decorum when the team management/leadership are players too?
I have handled it this season in this fashion. In the pre-game conference, I let the team representatives know that they are also responsible for their bench personel. Any problems from the bench that warrants a "T" will also be indirectly assessed to them as well. They wouldn't have to sit down, but the indirect would be added to the total number of personal fouls that they already have.
What do you think? Any other suggestions?
