After playing last year on a variety of second pairings with partners such as Andrei Markov, Nathan Beaulieu, and Alexei Emelin, Petry was thrust into a much larger role on the back end after Shea Weber suffered a foot injury early on in 2017-18.
With the defensive corps revamped and missing various pieces due to injury, Petry had some big shoes - er, skates - to fill. And by his own admission, the transition didn't go all that smoothly at first.
"It was definitely ups and downs throughout the course of the year. Looking back in September, I don't think I started the way I wanted to," confided Petry, who recorded a minus-11 differential in the first 21 games of the season, before Weber was on the shelf for the first time in mid-November. "I think my game improved throughout the year, and there are definitely things I need to work on and continue to focus on. One of those is my defensive game."
