Grew up on MA and RI border. Really just started getting into watching pro sports in 83-84, watching with my pop. 
			 
Mid 80s was a nice run with some horrible disappointments sprinkled in (86 sox, 85/86 patriots) 
That I remember: 
Celtics: 3 (F the 85 Lakers) 
Red Sox: 4 (F the 03 Yankees) 
Bruins: 1 (F the 13 Hawks & 19 Blues)
Patriots: 6 (F the Giants in general) 
So 14 titles in about 35 years of sports fandom of teams purely from my home city... albeit heavily concentrated recently.
90’s weren’t ideal.
