United States coach Richie Walker, who was an assistant under Suggitt when Kelter joined the team, noted a few key skills that translated from the rink to the pitch.
"She can scan a lot of the field and that also comes from hockey, where you try and pass the puck up to your teammates," Walker said. "She does a great job of exposing weaknesses in defenses. She's got really good vision, which adds to her good running lines. She does go into contact and she's really strong. She's the kind of player that just wants to go forward every time."
Walker said when Kelter came to the Olympic Training Center to try out for the team, he knew she had serious potential in rugby, but she needed to learn many of the rules.
"It was a little tough at first, but she has a real passion for the game," he said. "She will never let anything set her back. She practices and trains really hard, and even in her own time. So, when you give her a task to do, she'll go out and do it until she gets it right. I think playing other sports let her pick up things a lot better and a lot quicker. She is really good and works really hard and will do anything she can to make sure she gets it done properly."
Kelter said her teammates have helped her adjust to the game, and have made the transition a lot easier.
"Maybe about three or four months in, I really grasped rugby," Kelter said. "I'm still learning. There are things I still have to be reminded of constantly by my teammates. They're amazing. They've taught me everything."
There could be room for more current and former hockey players to take an interest in rugby. According to Walker, the gritty and tough hockey player style fits perfectly in the rugby sevens game. The two sports share a common need for speed, the ability to evade defenders and score as much as possible.
"It showcases America's talent," she said. "We're rough, we're tough, we're fast-paced and we're producing some of the best athletes in the world. I think having a great hockey team and rugby team will showcase that to the world.
"I truly think it's America's sport, and I think the fans will find out soon enough. Hockey is pretty big, too. I love it so much. I miss it every day. At the same time, I know that there's a lot of doors opening and closing for a reason, and I'm blessed to get another shot at an Olympics."
As for selling rugby to hockey fans, Kelter has a simple message: See for yourself.
"I think it's not going to need to be sold," she said. "I think people are going to see it and they're going to want to play it. You fall in love with it. You either love it or you don't. You either like tackling and like getting tackled and like hitting people, or you don't.
"If you love hockey and you understand the game and you see the side of mutual respect with your opponent and knowing it's an all-out battle out there and then afterwards you grab a beer or coffee and you hang out, you'll see it's the same thing with rugby. The camaraderie and teamwork and all that is the same, if not even more so."
