Scott Hamilton was one of them. Head here for loads more images of Mirai!
She was snubbed for Sochi in 2014 despite finishing third in the USA nationals as the selectors handed the Olympic berth to Ashley Wagner, who finished fourth.
Rippon had his own crusade for redemption, one that was the opposite of Nagasu's.
He did play it safe by substituting a double axel for the quadruple lutz that usually opens his program, mostly because missing the jump can be disruptive.
Clearly overjoyed, the 24-year-old Nagasu, who was skating at her second Olympics, pumped her fists and grinned as she skated off the ice.
Rippon was just thrilled to make his debut and help the USA move towards a medal in the team event.
Rippon had a new costume, newly-bleached white teeth that matched the costume and the ice, and in the last few seconds of his program, he knew that he was having the Olympic skate he'd always envisioned. Was he the right choice for the Games after botching Nationals?
Chen, the only male figure skater who's undefeated this season, perhaps needed the night off after his dismal showing in the team event's short program.
Everyone wishes they have the confidence that Rippon does.
He finished with 172.9 points, less than a point behind Russian skater Mikhail Kolyada and less than seven points behind Patrick Chan, part of the winning Canadian squad.
Rippon's routine was graceful and left commentators Jonny Weir and Tara Lipinski speechless.
Adam Rippon put together one hilarious interview after making his Olympics debut.
2014 gold medalist and six-time U.S. Champion Meryl Davis chimed in.
As previously reported, Olympic figure skaters are performing to music with lyrics for the first time at the Winter Games in Pyeongchang, South Korea, due to a recent rule change.
In the end, the US team got just about the best result it could have hoped for.
As Nagasu skated, she could hear Scimeca-Knierim's voice.
