Who are these guys? Getting to know the U.S. Olympic hockey team

There are a few faces you'll recognize on the United States' Olympic squad, but most of the players named to the initial American roster Monday are relative unknowns.

Thanks to the NHL's withdrawl from the 2018 Games, the U.S. team headed to Pyeongchang will be comprised of players from the AHL, NCAA, KHL, and other European leagues.

Here's a rundown of who these guys are:

Mark Arcobello

The journeyman forward played parts of four NHL seasons with five different teams, becoming only the third player in league history to suit up for four separate squads in the same season when he played for the Edmonton Oilers, Nashville Predators, Pittsburgh Penguins, and Arizona Coyotes in 2014-15.

He's in the midst of his second straight productive campaign with Bern in Switzerland's National League.

Chad Billins

This 28-year-old defenseman plays for Linkopings in the Swedish Hockey League and spent last season with the AHL's Utica Comets. He's played in Europe for four of the last five years and his NHL experience amounts to a mere 10 games with the Calgary Flames back in 2013-14.

You may recognize this blue-liner's name, considering he played parts of five seasons in the NHL with the Predators and Minnesota Wild, and also because the Predators drafted him 23rd overall in 2007. He's spent the last three seasons with the KHL's Admiral Vladivostok.

Will Borgen

This 21-year-old defenseman is in his third campaign at St. Cloud State and was a fourth-round pick of the Buffalo Sabres in 2015.

Chris Bourque

Ray Bourque's son was a second-round choice of the Washington Capitals back in 2004, but the winger hasn't been able to stick in the NHL for more than 20 games in any of his four campaigns. He's been in the AHL for the last four years.

Bobby Butler

This 30-year-old winger has played for the Ottawa Senators, New Jersey Devils, Predators, and Florida Panthers, but he hasn't seen NHL action since 2013-14 and has spent this fall and winter with the AHL's Milwaukee Admirals after a couple of years overseas.

Ryan Donato

Donato is a legitimate NHL prospect, and he's been lighting up the college ranks with 12 goals and 20 points in 12 games for Harvard this season. The Boston Bruins second-rounder is the son of former Bruins forward Ted Donato.

The longtime Devils, Montreal Canadiens, and Sabres winger will be Team USA's captain at the Olympic tournament. He isn't playing professionally this season, but he's only a year removed from a 15-goal campaign with the Sabres.

Matt Gilroy

Gilroy won the Hobey Baker Award as the top college player in the nation as a member of the Boston University Terriers back in 2009. The 33-year-old has seen time with four NHL clubs but has spent the last four seasons in the KHL.

Jordan Greenway

Speaking of Boston University, Greenway is in his third year with the Terriers and has 17 points in 19 games. The 20-year-old left winger is a Wild prospect who was taken in the second round in 2015.

Ryan Gunderson

This 32-year-old defenseman has played for various clubs in Finland, Sweden, and Belarus since 2010, and he toiled in the ECHL and AHL before that.

Chad Kolarik

Once a seventh-round pick of the Coyotes, Kolarik has only six NHL games to his name, having played in Sweden, Russia, Switzerland, and Germany since 2010.

Broc Little

Little had some good years with Yale, but his college tenure was a long time ago. Since leaving the Bulldogs in 2011, the 29-year-old forward spent six years playing in Sweden and is now with Davos in Switzerland, where he's put up 19 goals and 31 points in 35 games.

This very late pick by the San Jose Sharks in 2006 has since had a few decent AHL campaigns and has played 88 games for the big club. But at 31 years old, he still hasn't proven capable of carving out a steady NHL role. The winger has 12 points in 29 contests with the San Jose Barracuda this season.

Brian O'Neill

O'Neill has spent the last two seasons with Jokerit in the KHL, following a five-year AHL career in which he made only 22 NHL appearances. He won the Calder Cup with the Manchester Monarchs in 2015 and played with Little as a Bulldog for three of his four collegiate campaigns.

Garrett Roe

Switzerland, Sweden, Germany, and Austria have been the hockey homes of this 29-year-old winger over the last five seasons, and he's currently playing for EV Zug in the Swiss National League, where he's piled up 37 points in 31 games.

Bobby Sanguinetti

Sanguinetti has plied his trade in Switzerland for the last couple of years after a two-year stint in the AHL and one KHL season. He played 40 games over two seasons with the Carolina Hurricanes, as well as five contests with the New York Rangers, but managed only six points in his brief NHL tenure.

Jim Slater

Slater played 10 seasons with the Winnipeg Jets/Atlanta Thrashers franchise after being taken 30th overall in 2002. He's been playing in Switzerland for the last three years.

Ryan Stoa

Stoa is a 30-year-old center who's spent the last five seasons in the KHL. He was a second-round pick of the Colorado Avalanche in 2005, but played only 37 games for them over two campaigns and appeared in only three contests for the Capitals before heading to Russia.

He's best known for his shootout prowess, scoring three times in the post-overtime session to beat Russia in the semifinals at the World Junior Hockey Championship last January, then notching the only shootout goal as the U.S. came from behind to stun Canada for gold.

The 20-year-old center is an Anaheim Ducks prospect in his third season with the University of Denver, with whom he won the national championship last spring.

Noah Welch

Fans of the Thrashers, Tampa Bay Lightning, Panthers, and Penguins might recall Welch, although his NHL career was less than memorable. The 35-year-old blue-liner has been playing in Sweden since 2011-12.

James Wisniewski

One of the most recognizable names on the U.S. roster has 36 points in 23 games for the Kassel Huskies of Germany's second-tier DEL2 league this season. He hasn't played in the NHL since suffering a devastating injury in the season opener while with the Hurricanes in 2015-16.

Ryan Zapolski

The lone goalie added to the initial roster has a .935 save percentage in 32 games with Jokerit this season. He's spent the last two years in Helsinki after playing three campaigns with another Finnish club, Lukko Rauma, and spending the three previous years in the ECHL.
