All three of Tuesday's games have given the winner a 3-0 series lead, and a chance to get the sweep. While the Stars wins over the Sharks have been the closest (two of the three came in overtime), they will have the first chance to eliminate their second round opponent when they play on Wednesday night.
There is a possibility that all three teams will pull off the sweep, and the second round will be over much quicker then the first round was. Round two could see three series over after just four games, while round one only saw that happen once, and had three series go to the full seven.
The Penguins are going the best of all the teams and are 7-0 in the playoffs so far. Theoretically they could win all 16 games to take the cup. Regardless they are at least doing much better than the 0-4 record that they put up in the post season last year.
