East

Pittsburgh Penguins (1) vs. Ottawa Senators (7) - Penguins in 6. (Revised after thinking on my gut instinct)

Boston Bruins (4) vs. New York Rangers (6) - Bruins in 6.

East

Chicago Blackhawks (1) vs. Detroit Red Wings (7) - Blackhawks in 6.

Los Angeles Kings (5) vs. San Jose Sharks (6) - Sharks in 5.
