With RNH on the 4th line, I'm not sure. The other 2 centers apart from Aho are good depth centers and I would put RNH on the 2nd line at least. Only other problem is depth defensemen, but other than that solid lineup.
Bust this is basically Calgary with Kucherov instead of Gaudreau (Calgary is horrible so with Kucherov they'd be like a fair team). They're not bad they're just meh. Though they have a lot of cap space
