The New York Rangers are deeper than the Washington Capitals in every way
The New York Rangers have a lot more depth than the Washington Capitals right now. At forward, defense, and goaltending, the Rangers have more players that make a bigger impact.
First off, there are the forwards. The Capitals have Alexander Ovechkin and Dylan Strome amongst other good young players but it doesn’t compare to the talent that New York has up front.
Everything with the Rangers in terms of scoring starts and ends with Artemi Panarin. He was one of the best offensive players in the NHL and certainly the best in this series.
The Rangers have multiple other great forwards like Chris Kreider, Alexis Lafreniere, Vincent Trochek, and Mika Zibanejad amongst others. All of these guys score tons of goals and drive play at a high level.
On defense, the Capitals have John Carlson. However, the Rangers have Adam Fox, K'Andre Miller, and Jacob Trouba. The depth beyond that even favors New York and it isn't close.
In goal, the Capitals had some good play from Charlie Lindgren but he isn't close to Igor Shesterkin. The latter had a tough start to the season but he bounced back strongly after the All-Star break. When he's on, he is one of the best in the NHL.
