Nine players have dressed with the number 15 on their back for the New York Islanders. The first to ever do it is our winner today, spoiler, so I'll start by talking about some other notables to wear the number.
Brad Dalgarno, Brad Isbister, Jeff Tambellini, P.A. Parenteau, and most recently Cal Clutterbuck have worn the number 15. Trying to come up with an honorable mention for this one wasn't easy but we're going to go with Brad Isbister.
Isbister spent four years with the Islanders in the early 2000s playing 247 games for the organization.
