Just something to do on the night before Thanksgiving.  I got tired after checking back to the 1967 76ers.  Only one team in a full 82 game season since 1967 had an 8-7 record after 15 games and won an NBA title, the 1978 Washington Bullets (who finished 44-38 that season).  Any earlier than that, the season gets a little shorter.
