The Penguins have added some serious size over the past two years. McGroarty is a strong forward who can knock guys down and use his frame to generate scoring chances.
Bill Zonnon and Will Horcoff love to bring their energy to every shift, and I can see them becoming valuable bottom-six options.
Peyton Kettles, meanwhile, is 6-foot-5 and makes it hard to get around him. I can see them all becoming NHLers, and that alone should make them a bit more scary to play against.
