I think about him all the time, especially when I'm racing.
Among the 244 USA athletes participating in PyeongChang, none is more famous, more photographed or more scrutinized than Vonn.
Lindsey Vonn broke down in tears on Friday as she vowed to win a second Olympic gold medal in the memory of her late grandfather.
"On any World Cup it's hard to predict the victor... but here there's one downhill every fourth year and then it really gets a lot of focus and if there's a prize you remember it longer". I know it's a comparison between sports and I don't think there's a sport in the Winter Olympics where you can even win 23 medals across three or four Olympics.
'He's been such a big part of my life.
"I think the mistakes will come from pushing too hard, because when it becomes difficult to win, guys try to take too much risk to try to gain that little bit extra", added the 40-year-old Miller, working as a broadcaster during the Games. "I know what I am capable of and I can handle myself better than I did", she said.
The 22-year-old slalom gold medalist from Sochi has racked up 10 World Cup victories this season but has managed to reach the podium just once in her last six races, a disappointing dip she attributed to fatigue.
But, after Vonn dabbed away her tears with a tissue, know who stole the show at a packed press conference? "Then I have to bike, I have to stretch, I have to do all these extra steps that I didn't have to do before", she said. You might say she is keen to repeat.
And that's why Lucy can be the X-factor in this quest for Olympic redemption. Lucy is a ski-racer's best friend. "She enjoys sleeping a majority of the day". "It's extremely lonely on the road ..."
"Being in a hotel room is often at times extremely hard". So I got Lucy.
"I would like to compete in everything", she said.
That made it tougher to concentrate fully, tougher to be at her best and tougher to be what she had proven to be for quite some time, which is the best female Alpine skier in the world - and with the trophies to prove it.
A dog wags it tail, whether you bring home a gold medal or not.
"It's not a training run that tells you very much", he said, listing the shortened course, the shifting tailwind and a shaved down last jump.
A dog, which never bites the hand that feeds it, is more trustworthy than a Tiger.
Vonn was only 17 in her first Games in 2002 in Salt Lake City.
"Because of the schedule and because it's my last Olympics, it's very important to me to attend", she said, "and I'm going to get as much of the Olympic experience in these next two weeks as possible".
Austria's defending Olympic champion Matthias Mayer said the course was "much easier" than the icy challenge that was the downhill in Sochi.
