      It would all be easier if the leagues started just recording team
      possessions as several coaches do in college and high school. I
      certainly didn't invent the concept of possessions. Dean Smith might
      have been the first, though even that is debatable. But he was doing
      it for Frank McGuire at UNC in the '50's and continued having an
      assistant do it throughout his tenure there. His disciples and
      numerous others in college hoops have tracked this on their own. It
      is a very USEFUL number for us. It is pretty innocuous to most fans -
      - "what is this for?"

      I actually do have a breakdown of team rebounds and team turnovers
      for last year (I am waaaaay behind in doing so this year). Do I use
      it? Not so much. As JohnM said, it would be useful to get stuff
      like this for the calculation of possessions, but simply tallying
      them would be best and easiest (the league already has official play-
      by-plays and could count alternates in possession to get possessions).
