The Lightning were able to manage the injuries last game, but a whole series without key players could be costly. Players battle through injuries all the time in the playoffs, and the Lightning are used to it at this point. 3 cup appearances in the Stanley Cup Final will wear you down, and right now it's showing.
The Maple Leafs have a full healthy roster, and should be taking advantage of the Lightning's depleted roster. But if this Tampa team has shown us anything, it's that they know how to battle adversity.
