Is Game 7 a defining moment for Ovechkin?

The debate of “Who’s better: Sidney Crosby or Alex Ovechkin?” is a thing of the past – or at least it’s been put on hold for the moment.  But the biggest knock on Ovechkin has always been his inability to win the big game compared to Crosby’s ability to do the opposite.  And it’s safe to say Ovechkin is staring at a big game tonight.The Washington Capitals had a chance Sunday to knock out the defending champs, but Tyler Seguin had other ideas.  But even if the Washington Capitals lose tonight’s Game 7 in Boston, it still won’t match the immense disappointment from their collapse in 2010 against eighth-seeded Montreal.  Also, tonight won’t be the biggest game Ovechkin has played in or will play in his career.Don’t discount the importance of this game, though, for the Capitals captain.Since the Capitals have become a regular postseason participant back in 2008, they have played in their fair share of Game 7’s – four to be exact, all at home.  They have won just once, back in 2009
