Sidney Crosby knows there isn't much that separates his Pittsburgh Penguins from the rival Washington Capitals.

Despite having beaten the Capitals in each of the past two postseasons on the way to back-to-back Stanley Cup wins, Crosby doesn't see anything different in Washington this year. That's to their credit, he adds, acknowledging how slim the margin of error is when these two clubs face off.

"I thought they were pretty relentless the last couple years, too," Crosby said Monday, per Isabelle Khurshudyan of The Washington Post. "The games are separated by one goal here, mistake here, mistake there. I didn't see them give in before. That's an easy storyline because we ended up winning."

The Penguins face elimination entering Game 6 of a third straight second-round series between the two clubs; last year's series went seven games, while Pittsburgh won in six back in 2016.
