And there is the fact that anyone or all three could be gone next year. Al and Kyrie both can opt out and Smart might be salary filler in a trade. Yes the various chances of any of those three not being on the team are different, but there is still a chance they could be gone.
It's obvious that the captain should be smart or horford, but most of the team looks to Kyrie.
That's been a major issue all year.
It's possible that actually naming one of those guys captain would give them a sense of credibility beyond the natural credibility they have by virtue of their experience/dedication.
If something like that were to happen (I think Stevens has already said he doesn't believe in captains so it doesn't look like it ever will) I would expect it to be a mid-season deal.
