Getting back to the OP, by my count Boston (including the NE Patriots) has won 7 North American professional mens sports title in the 10 years from Fall 2001 (actually Jan/Feb 2002) through June 2011. That’s good, but not the best record.
Cleveland won 8 from December 1945 through December 1954. (Browns 6, Indians 1, Rams 1). Browns also won in 1955, making it 9 titles in 11 years.
Los Angeles won 8 from June 1980 through October 1988 (Lakers 5, Dodgers 2, Raiders 1)
New York (including Meadowlands and Long Island) won 8 from June 1973 through June 1982: (Islanders 3, Yankees 2, Nets 2, Knicks 1). Islanders also won in 1983, making it 9 titles in 11 years.
Montreal takes the cake though, winning 9 championships from 1970 through 1979 (Canadiens 6, Allouttes 3).
Edmonton gets 6 football championships from 78-87, plus 3 hockey championships for 9; stretch it by one year and you get one more hockey championship, and stretch it by 3 and you get 2 more.

This disappointed me no end when I learned of it. My favorite Japanese baseball team name was the Nippon Ham Fighters; I had always thought that “Ham Fighters” was the most awesome team nickname ever. But, noooo, it’s the Fighters, owned by Nippon Ham!
The Fort Wayne Pistons (now in Detroit) were founded and owned by the Zollner Piston Corporation in Fort Wayne before they eventually moved to Detroit.
Look at the list of NBL (National Basketball League) teams: National Basketball League (United States) - Wikipedia
My personal favorites are the Toledo Jim White Chevrolets and the Akron Firestone Non-skids.
