Kirwan said he was "working in the front office one day, then was in the locker room the next and I had no idea what I was doing."
"I knew hockey, but I knew nothing about video, what I needed to do, what the job entailed," he said.
Today Kirwan is one of the NHL's longest-tenured and most-respected video coaches. Tampa Bay forward Pierre-Edouard Bellemare said he's amazed Kirwan has been coaching for so long.
"He's as aware of our system as the other coaches and his advice is valuable," Bellemare said.
"If Nigel comes and tells me, 'Hey, you're not playing the right way,' I would probably ask him, 'All right, please show me clips so I can get better.' It wouldn't be like, 'Aw, he's a video coach.'"
Lightning CEO Steve Griggs said Kirwan's longevity is an inspiration.
"I think young men and women of color can look at someone like Nigel and say, "I can be him, I can do that," Griggs said. "Whether it be (Lightning) chief operating officer Mark Pitts (the NHL's only Black COO) or Nigel Kirwan, they can aspire to those roles within what is somewhat of a predominantly white sport. This creates visibility and opportunity for those who say, 'That's what I want to do.'"
Kirwan said he still can't believe it has been 30 years with one team and more than 2,000 games with Tampa Bay.
"And three rings, that's even more remarkable," he said. "It's a blessing to win one."
