Just from his Islanders days alone, there are too many moments to rank, from calling three of the four Stanley Cups championships, to the 1987 Easter Epic, to the 1993 underdog run to the conference finals.
"That's like saying which one of your two girls do you like the best," Jiggs joked.
Those are top-tier moments for McDonald, but what really stands out are the people he's met along the way.
"I reflect on the people I've met; some of the best people in the world are involved in this sport, that's what makes this game so great," McDonald said.
People like Eddie Westfall, who spent 15 years alongside Jiggs in the booth after advocating to bring him to Long Island. McDonald knew Westfall's family, so it was a much appreciated gesture for the former Islanders' captain-turned commentator to vouch for him. McDonald said they had a tremendous relationship and a lot of magic moments on TV together.
