USA, Canada, Europe, North America Announce Final World Cup of Hockey Rosters

The final rosters for the 2016 World Cup of Hockey were revealed Friday, with all eight teams announcing their last additions, per ESPN.com's Scott Burnside.

Team Canada, which looks to be the favorite, added bona fide stars such as Brent Burns, Claude Giroux, Alex Pietrangelo and Joe Thornton to a loaded roster.

Los Angeles Kings defenseman Jake Muzzin was a surprising choice over Canadian international stalwarts such as Brent Seabrook. Other stars were also left off, per SportsNet's Chris Johnston:

Muzzin will likely reunite with Drew Doughty, his partner on defense for much of the last two seasons. Muzzin put up a decent total of 40 points this past season, but his team-leading five points in five playoff games may have earned him a roster spot.

Team USA again looks solid, but it made a few questionable final decisions with its forward group. Columbus' Brandon Dubinsky and Tampa Bay's Ryan Callahan will join the roster, but some established scorers were left off, which ESPN noted:

Phil Kessel is leading the Eastern Conference champion Pittsburgh Penguins in playoff scoring with 18 points, and he has proved to be an elite forward during his career. Team USA may have wanted to add some defensive forwards such as Callahan and Dubinsky to combat the superstars Canada will put on the ice, but the Americans should have found a spot for Kessel.

Team North America will be an interesting group with young stars such as Connor McDavid and Nathan MacKinnon, but the most surprising name is Auston Matthews.

He was added Friday before even becoming an NHL player. He is expected to be picked first overall by Toronto in next month's draft. North America apparently saw enough from Matthews at the World Championships to give him a spot.

Sportsnet's Eric Engels seemed to be skeptical:

There were no huge surprises with Team Europe. Islanders goaltender Thomas Greiss did enough during his team's playoff run to earn a spot, per ESPN, but he and Los Angeles' Anze Kopitar will lead a group that looks like a long shot to win the tournament. 

The Czech Republic, Finland, Russia and Sweden released their final roster earlier in the day, per NHL.com. The biggest story from these teams was Russia leaving off Ilya Kovalchuk in favor of defenseman Slava Voynov.

Voynov was suspended for all but six games of the 2014-15 season after an alleged domestic violence incident, and he subsequently left for the KHL. Voynov's inclusion is even more questionable because the NHL may ban him from playing in the tournament, per Burnside.

Each team announced its initial 16-man roster in March. 

The tournament will begin September 17, and it should be a tremendous appetizer before the NHL season kicks off in October.
