Which North America professional sports team has won the most consecutive championships?

The Boston Celtics won 8 NBA championships in a row from 1959 to 1966, with Red Auerbach as head coach.

They were founded in 1946 as one of the original 11 teams: Boston Celtics, Chicago Stags, Cleveland Rebels, Detroit Falcons, New York Knickerbockers, Philadelphia Warriors, Pittsburgh Ironmen, Providence Steamrollers, St Louis Bombers, Toronto Huskies and Washington Capitols.

The Celtic franchise is the most successful in NBA history, with 17 championships, which accounts for 23.9 percent of all NBA championships since the league's founding.

They have had many Hall of Fame inductees, including Bob Cousy, Bill Russell, John Havlichek, Pete Maravich, Dave Cowens, Kevin McHale, Larry Bird, Robert Parrish and most recently, Jo Jo White. Shaquille O'Neal also played for them in the year prior to his retirement.

Modern day consecutive championship wins are more difficult to achieve with free agency, salary caps, draft selection and player mobility being among the aggravating factors.

But the biggest challenge may well be the number of teams in the various professional leagues today. The NBA had only 8 teams in 1959, 10 in 1966 and presently have 30.

When the Montreal Canadiens won the current record of 5 Stanley Cups in a row, there were only 6 teams in the NHL. There are now 31.

Similarly, the New York Yankees run of 4 championships happened in an era of 16 teams as opposed to the present-day 30.

No NFL team has won more than 2 Super Bowls in a row.

Yes, it is true that no NFL team has won more than two consecutive Super Bowls, but the NFL started 47 years before the first Super Bowl. The Green Bay Packers have won three consecutive NFL championships twice.

Somebody didn’t do their homework. How could you miss the Rochester Royals ? The Royals won the 1951 NBA title ,if memory serves me. My dad was a close friend of Les Harrison ,and I grew up at a very young age in the locker room,if you could call them that. I knew Bobby Davies,Arnie Risen,Bobby Wanzer ,and of course Red Holzman ,who went on to coach the Knicks . It’s peculiar how you can recall certain things from the time you were five or six years old. My dad passed away in 1987 , the game was changing even then in a big way. He would always remark on the twenty four second clock , which was soon to adopted after the Royals win. The Royals would get the ball, and had very good guards that would dribble ad nauseum if the Royals were up in the fourth quarter , basically running the clock out, or get fouled doing so. Now I live in San Francisco, what can I say. Golden State will be moving from across the bay next year, and we’ll have the Warriors in our backyard . It will be interesting to see how history favors Curry in ten ,fifteen years at most ...
