Indeed. Maroon is the safe option. But on the flip side selecting Gryz and mixing up the lines unnecessarily were not. Which suggests some muddled thinking on Monty's part. The players are scared of losing again, I think that's pretty apparent. But I strongly suspect the coach is too.
Probably the best thing he can do for G6 is keep it simple. Go with the lines that are tried and tested and have worked best over the course of the season, keep Sway in net, don't keep overusing a guy like Maroon just because it calms your jitters. Get the narrative away from the bench and just allow the players to go and take care of business on the ice. If they can't, well so be it. At least you can say you weren't a hindrance.
