There are six games on the Sunday schedule in the NHL this week, and four of those six matchups are within the East Division.
A quick glance at the standings shows that a "Big Four" has emerged; while the New York Rangers are finishing the season out strong, the team they're chasing for the final playoff slot -- the Boston Bruins -- has a four-point lead with two games in hand. One of those remaining games for Boston is hosting the division-leading Washington Capitals at high noon ET on Sunday.
