Try to get by without a great goaltender in the NHL, and you are fighting a losing battle.
Average to good teams can become great when they receive a superior performance from a goaltender. On the other hand, excellent teams can become ordinary if the goaltender fails to perform.
No goaltender put on a better show last year than Sergei Bobrovsky of the Columbus Blue Jackets. He carried the team on his shoulders and nearly led them to a spot in the playoffs. He won the 2013 Vezina Trophy.
Bobrovsky should be a prime contender for the award again this season. However, he's going to have to hold off the likes of Henrik Lundqvist, Jonathan Quick, Pekka Rinne and Tuukka Rask if he is going to repeat.
Here's our look at the top candidates for the 2013-14 Vezina Trophy.
