There are two familiar faces left standing in the 2017 NHL playoffs, but the conference finals will welcome two teams that few expected to make a run at the Stanley Cup when the postseason began.
The Pittsburgh Penguins are back in the conference finals after once again dispatching an outstanding Washington Capitals team, but the Ottawa Senators look capable of pulling off another upset in their stunning run.
In the West, the Anaheim Ducks beat the upstart Edmonton Oilers, but the Nashville Predators are a legitimate threat to advance despite entering the postseason in the last wild-card spot.
