The 1981-82 Celtics had a winning streak of 18 games. It started with a win over the Utah Jazz (132-90) on February 24, 1982 and ended with a loss to the Indiana Pacers (102-101) on March 28, 1982.At this time the celtics had great legend players.
They won 9 in a row in 1980, that is the longest I can find. They are on an 8 game winning streak now, in the 2010 season, with 2 games remaining. The Falcons won the last 9 games of their 1998 season. They went on to win two playoffs for a Super Bowl appearance where they lost to the Denver Broncos. That would make an 11 game streak including post-season play. In 1980, in a 12-4 regular season, their 9 game winning streak ended when they lost the last game of the season. They were eliminated in the first round of the playoffs.
The Chicago White Sox.
