Boston's domination of the sports landcape

Congratulations to the Boston Bruins on ending their three decade long drought for the Stanley Cup. Remarkably the teams representing the Boston area have won championships in each of the four major sports in the last 7 years. Is there another city that has done so in such a short time frame?  I can't think of one.  Remarkably the Patriots now have the longest championship drought in the Boston market. On twitter we came up with a few who had 3 in short period of time.

Mets, Jets and Knicks won in 69-70

Oakland had Warriors, Raiders,A's 74-77

Mets, Islanders, Giants did it 83-86

Yanks, Giants and Rangers from 91-96.

Any others?

Darren Rovell of CNBC points out that up until 1993 the longest drought Canada had was five years but now they haven't won one since 1993.
