I like the idea of having a line of Bratt-Hughes-Holtz that can generate high danger chances off the rush and having another line of Slafkovsky-Nico-Mercer that can be a nightmare along the boards.Nico is good along the boards himself. I would rather him with a really fast skilled winger in Bratt and Hughes with the big skilled winger in Slafkovsky
Ultimately I think all these players will move around but having different lines that can beat you in different ways is intriguing.
