Error Note: For the games from 1990 and before, I used the boxscores
that were in the Dallas Morning News (which were the same as those in
the Dallas Times Herald).  The computed season totals had some variants
from the official season totals listed in the Mavs media guide.  Those
variants are:
                                    Official  Boxes
  Season  Stat                       total    total  Difference
   1988   Derek Harper minutes        602      606      -4
   1988   Brad Davis minutes          295      291      +4

   1987   Opponent turnovers           53       52      +1

   1986   Detlef Schrempf minutes     120      121      -1

   1986   Dallas steals                66       65      +1

   1984   Dale Ellis assists            4        5      -1
   1984   Dallas assists              217      218      -1
   1984   Dallas turnovers            131      130      +1
   1984   Opponent turnovers          133      131      +2
   1984   Opponent fouls              255      258      -3
   1984   Opponent steals              64       63      +1
 
Of course, I don't know which boxscore (and, thus, which series)
contains the actual error.  Most likely the Dallas and Opponent 
turnover variances are due to team turnovers not being listed.
