1. They have a rookie goalie
The Capitals will have 22-year-old Braden Holtby in goal for Game 1. That can either be an advantage or a disadvantage for Washington. Holtby has made 21 career NHL appearances and has never appeared in an NHL playoff game. Either he'll freeze in the headlights and cost his team a game or two, or he'll seize the moment, forget what kind of pressure there is, and steal one from the favored B's.
