Actually, I just did another scenario in the new CapGeek calculator that allows to use bonus cushion and we're looking good.
I think there's a good balance on each of three first lines. Passer (Backstrom, Ribeiro, Johansson), scorer (Ovechkin, Wolski, Barkov), grinder/defensive specialist (Forsberg, Brouwer, Laich). Having Chimera and Ward on the fourth allows more flexibility for Ribeiro line first of all. If things don't click, you just swap Wolski and Brouwer with Chimera and Ward and you have a new look.
