McDonagh spent parts of eight seasons with the Rangers, beginning in 2011 following his promotion for Hartford (AHL) in January until his trade to Tampa at the deadline in February.
Girardi, meanwhile, played nearly 800 games as a Ranger over parts of 11 years, beginning in the 2006-07 season after signing as an undrafted free agent.
The two will be forever linked together as the Rangers' top pairing for most of the organization's successful run from the start of the 2011-12 season through last year. Girardi was bought out of his contract in June 2017.
"They were our No. 1 pair. They always had the toughest assignment. They thrived on that," Vigneault said of Girardi and McDonagh. "They wanted to go up against the best players in the league and compete and work hard. I've got nothing but total respect for those two. They always came and gave 100 percent. There was never any excuses. Very accountable to their performance. Very accountable to their teammates and that's what you want from your players."
Forward Mats Zuccarello, the fourth-longest tenured Ranger behind Henrik Lundqvist, Marc Staal and Chris Kreider (though Zuccarello joined the Rangers a season before Kreider, but spent time in 2013 in the Kontinental Hockey League) expressed his respect for McDonagh, not only as a player but as a friend.
"It's going to be tough for sure. He's a guy that had been here my whole career since I became a Ranger," Zuccarello said of McDonagh. "He's been here with me and we kind of went the same path down to the AHL together and called up almost at the same time.
:He's one of my good, good friends and I miss him when I look around the lockeroom. To see him on the other team is going to be tough for sure. At the end of the day, we didn't have a good season here with the Rangers. We didn't make the playoffs. It's tough, but I'm just happy for him that he gets to play in the playoffs and play on a good team. It's good to see."
