So you are asking about one year championships across multiple sports? Not just all time historical multi-sport championships for a city?
The gap between the Boston championships is longer than I remembered. They just won so many it's hard to keep them all together chronologically.
They had a 10 year window of
Patriots '04, '05,
Celtics '08
Red Sox '04, '07, '13
Bruins '11
So their closest window was Red Sox '07 to Bruins '11. Still pretty crazy.
