I don't really agree on the play styles being different. I think both Gryz and Lohrei are puck movers. Gryz roves in the offensive zone as much as McAvoy. Some of the best hockey I've ever seen was when Marchand, Bergeron, Pasta, Gryz and McAvoy were on the ice together. No positions, everyone weaving and roaming, guys interchanging... it was impossible to defend. I think Lohrei likes to rush/carry more and I think Lohrei is a more natural scorer. He's also 6'5 so he's like Super Gryz in my mind. Everything you like about Gryz but with Carlo's body.
I also don't think they're big believers in Grzelcyk's pk ability. Honestly, I don't think Monty is a fan of Gryz, period. Gryz plays less under Monty than under Cassidy, Monty scratched him in the playoffs. I think Monty prefers Forbort, for the role that Forbort plays, which is why I worry that if they keep Lohrei and Gryz, Grzelcyk will be the one sitting and hurting his trade value.
I think if they did keep everyone, and you could convince Monty to sit Forbort, the 1st and 3rd LD would be flipped from your lineup...
