Moore said what's exciting for him is the opportunity "NHL Mash-Up" has to educate fans about players who aren't on the team they might usually watch.
"Everybody follows their own team so closely," he said. "Maybe if you live in Toronto, you know Mitch Marner loves dogs. But maybe in Carolina, you get to see a little bit more of Mitch Marner's personality. I think everyone wins when fans get to see more of the personalities around the League."
Moore, an analyst for ESPN, will slide into a hosting role for the first time in his broadcasting career. He said being reunited with Tappen will make that transition easier. The two worked together at NBC Sports when it had NHL broadcast rights. That ended following the 2020-21 season.
"It's just basically follow Kathryn's lead," Moore said. "Kathryn carried us at NBC for a long time. She's so amazing at what she does, and it's fun for me to try a new side of things."
Tappen said she was excited to get back into hockey. She was an NHL Network host from 2011-14 before joining NBC. In addition to her duties there, she worked on the TNT broadcast of the Calgary Flames-Seattle Kraken game Dec. 28.
She's hoping "NHL Mash-Up" can lead to more NHL opportunities.
"I'm super energized," she said. "Everybody saw when I came in this building today, just the smile on my face. The car ride in I was excited. Just getting choked up thinking about it. It's been a while that I've had the opportunity to continue to be a part of the NHL … now getting an opportunity to do this show and coming in here, it just feels right. It feels like home."
