If they really want us to ask for captains in the pregame meeting and note that in the book, apparently establishing this as a means of identification in case communication is necessary during the game (as if we won't communicate with anyone else, but that's another topic), and ask them before the jump ball if their team is ready then do what they do in soccer and have them wear an identifiable armband up above the elbow. Otherwise, get rid of this "captain" thing and allieviate us of this "eight captains at the pregame meeting" (I wouldn't mind if they all came) and the "that guy" thing of having to distinguish between the somewhat ceremonial captains versus the "speaking captains".
(OK, there is a nice objective fulfilled by a coach vesting responsibility as captain(s) in the current system, but that would survive and be even more illustrative with the armband thing).
If it's to be implemented, give it some relevance, significance, and practical use.
