Despite the lingering effects of the injury, which hampered him greatly towards the end of the year, Grzelcyk has no regrets about pushing through the pain.
"It was torn enough that either do [the surgery] right then or at the start of the season, knowing that [the shoulder] was going to come out a couple of times - it was inevitable," said Grzelcyk "But I would do that all over again for sure, just to be back on the ice with the guys.
"Anything you can do to join them. Not wanting to give up; that was my mindset and, unfortunately, just kind of snowballed by the end…you don't have as much time to recover in the playoffsso it got tough."
The 5-foot-9, 178-pounder said he has already spoken with new coach Jim Montgomery about ways to better protect himself, particularly when it comes to going back to retrieve pucks in the defensive zone.
"Just seeing it on video. I met with Monty a couple times, just kind of showing me to pick and choose my battles a little bit," said Grzelcyk. "You always want to compete. At the same time, you have to be smart about things, too. Just knowing when to want to jump in the corner at the right time or when to take a hit to make a play, that's what you're always taught as a kid, so that will never change.
"But there are definitely some areas they can just be more mindful of going back on pucks. I think that's kind of what happened for me. I put myself in a bad position, so I definitely have some learning to do."
Grzelcyk has also been working alongside new assistant coach John Gruden - who was his U-18 coach at the United States National Team Development Program in the early 2010s - to find areas of improvement within his game.
"Whenever we played the Islanders, [I would] catch up with him for 20 minutes or so. He's a great guy," said Grzelcyk. "Just a lot more about jumping up in the play, just kind of switching your mindset that way. We haven't watched a ton of videos as a team as much yet, but that was mostly from clips where we watched some breakouts together.
"If I just dish it to my partner, I can know that I can kind of get up in the play a little bit more and not hang back. So, that's always exciting for me. I just want to add a little bit of offense and hopefully I can jump right in when I come back."
