Here is the statistical breakdown of the regular season head to head match up between the Washington Capitals. (click to enlarge)
As you can see, Washington seemed to have their way with Tampa Bay in the regular season, at least until Dwayne Roloson arrived from Long Island. Roli the goalie needs to steal this series for the Bolts, but I do not see this happening. Washington should win this series.
Should Washington be able to finish off the Lightning quickly (let's say in 5 games), the Caps will be even stronger Stanley Cup threats than at the beginning of the playoffs simply because of their path. The Rangers rolled over and died and allowed the Caps to recover and relax before round two. That rest will become increasingly valuable as the playoffs continue.
Meanwhile in the West, the favorites keep colliding in epic battles. By the time someone wins the west, will they have anything left?
