Sidney Crosby has been widely considered to be the best player in hockey throughout the majority of his career.
He has the bona fides that confirm his status. He led the Pittsburgh Penguins to a Stanley Cup Finals appearance in 2008 and while they were beaten by the Detroit Red Wings, they made it back to the finals the following year and the Penguins got revenge over the Red Wings.
He confirmed his status when he scored gold medal-winning goal for Canada in the 2010 Winter Olympics.
However, nobody stays at the top forever and Claude Giroux was nominated by his head coach Peter Laviolette as "the best player in the world" when the Flyers defeated the Penguins in a playoff series last spring (source: Yahoo.com).
Let's look at the specifics of the matchup in this head-to-toe breakdown of these two Keystone State superstars.
