from Greg Wyshynski of ESPN,

Madison Square Garden, home of the New York Rangers, is 11 miles away from Newark, New Jersey's Prudential Center, home of the New Jersey Devils. They are separated by a river. They are bonded by an intense, decades-long enmity.

The Battle of the Hudson is one of the NHL's most storied rivalries. For the first time since 2012, the Rangers and Devils will face each other in a playoff series, beginning tonight in Newark. It marks the seventh time these franchises will have met in the Stanley Cup playoffs, with New York holding a 4-2 lead in series victories.

The animosity between these unfriendly neighbors extends from the fans to the players to even their front offices -- consider that the Rangers and Devils made their first trade together in 2018.

"The hatred? I couldn't even put a number on it. The hatred was off the charts," said Ken Daneyko, who played 20 seasons with the Devils before becoming a broadcaster for the team. "It was an unwritten rule that you wouldn't even say their name. I imagine it was the same thing for them. It was that kind of rivalry."
