Curling-How alternates support their teams from behind the scenes

CORTINA D'AMPEZZO, Italy, Feb 11 : At the Winter Games, a group of curlers exist in a strange paradox: officially Olympians yet uncertain whether they will set foot on the ice.

These are the alternates, the unsung fifths in a sport designed for four.

"My goal is to be always wanted or needed but unnoticed," said Tyler Tardi, the alternate of a Canadian team led by 2014 Olympic champion Brad Jacobs. 

"If I can be behind the scenes, but the guys know that I'm making their lives easier, that's all I can do and that's all I can want. It's one of my personal traits I think, selflessness. It is a big goal of mine to put others ahead of myself. That fits this role pretty well."

The 27-year-old is keen to learn as much as he can from his teammates, who have a wealth of Olympic experience.

"To finally be at the Olympics and to not be on the ice, I don't take that as a negative," he added.

"It's more so of a driving force for the future. We're only a few days in and I already want to be back. This is super cool. I can't wait to work hard and try to be on the main lineup in the future."

THROWING ROCKS

One of the main responsibilities of an alternate is to throw rocks the day before a game and map out how each individual stone travels on the ice.

"The rocks run a little bit differently sometimes," said U.S. alternate Rich Ruohonen. "That's the main thing. Also, just doing anything I can to help the team. Carry the brooms, go make sure everybody's up in the morning, make sure people are where they need to be when they need to be there, change the broom heads before the game.

"I'll re-watch certain shots in the game, I also scout the next team. There's just so much strategy involved."
