This Wikipedia page includes last year's captains for most teams: http://en.wikipedia.org/wiki/List_of...A_team_rosters
No real surprises; however, Damian Lillard was a co-captain in his rookie year. Pretty interesting given the other vets on that team (Batum, Matthews), but he definitely appears to have some good leadership qualities.
Also, at first, I was like "What?! Goran Dragic, captain?!", but then I looked at the rest of Phoenix's roster... #poorsuns
edit: For a good laugh, check out Sacramento's supposed captain.
