Grzelcyk, who resumed skating on June 15, noted that the testing and health protocols that have been required during Phase 2 of the NHL's Return-to-Play protocol have been "pretty tedious," but quickly added that the precautions are necessary to ensure the safety of the teams' players and staff during these uncertain times.
"I think the league and the team are taking all the right measures to have the players stay as healthy as possible, and staff coming to the rink, keeping them in mind," said Grzelcyk, who posted 21 points (4 goals, 17 assists) in 68 games during the 2019-20 regular season.
"It's been tough on everyone, but I think that we're trying to do the best we can to make it a safe environment and really learn some things in this phase here and hopefully it will make us better moving forward."
The Charlestown native has been part of a skating group that includes Torey Krug, Sean Kuraly, Patrice Bergeron, and Brad Marchand. Grzelcyk said they have been taking things slowly but that he's been encouraged by how well he has felt thus far, despite being off the ice for such an extended period of time, which he estimated could be the longest such stretch of his career outside of a knee injury prior to his senior year at Boston University.
"I was a little nervous, to be honest, hopping on after not getting a chance to go on for three months, really," said Grzelcyk. "I was kind of pleasantly surprised at the first couple times. That was nice - probably due to the fact that we were into the full swing of things in the season and still had that mentality with that date [July 10] thrown out there for when training camp might start.
"That's given me at least some more clarity in things when you need to be ready by. It's been good. It's been a joy to get back out there and see some of the guys again. Just go have fun and break a sweat. It's been great mentally even more so than physically. Hopefully things keep going well in that expect."
Grzelcyk added that the Bruins' veteran core has taken the lead in organizing the skates which are limited in their length and scope given the Phase 2 restrictions that require strict time constraints to fit in each group and prevent coaches from being on the ice.
"You expect to have a little rust and you know it's gonna be a challenge coming back," he said. "Some of the older guys have drawn up their own drills or maybe consulted with [skating and skills consultant Kim Brandvold] going into days. But we've had a good pace to it.
"We realized that you don't have a ton of time at the rink and you want to be respectful and leaving enough time to have the next group come in and everything be a safe environment for everyone to step back into. It's been fun to do different drills and twirl around for sure."
