Wow, this is so sad. What a legend. I only have three first cousins and they all grew up on Long Island. The middle one (12 years older than me) came of age during that great Islanders Stanley Cup run. He had all sorts of neat Isles memorabilia and books, so I grew up hearing of the legends of that team.
That cousin took me to my very first NHL game (Islanders, naturally) in January 1989 and thus I didn't get to see Bossy play. Trottier, yes.
RIP.
