"I have to be honest, I didn't know she was going to be as good as she was," said Corby.
The US hasn't won a single medal yet in long distance speed skating during the Winter Games. Corby is hoping the women bring home some hardware in the team pursuit event.
"Hopefully they can knock off a half a second and pull out a medal," said Corby.
He said the future looks bright for US Speed Skating. Erin Jackson was an in-line skater who was not even training on the ice six months ago and won a spot on the US Olympics team at the Milwaukee trials.
"She's got a huge future ahead of her. Watching her skate your like, 'There's a technique flaw. Oh, you got to do this. Oh, you got to that.' And she's still competing against the best in the world. When she corrects all that stuff she is really going to see a lot of success," said Corby.
He said watching her in 2022 is going to be even more exciting.
