How far does this team go

Stanley Cup.

D is a little weak compared to the rest but the forward corps literally has 4 hart contenders (okay Kane was last year, whatever) and G's have a Vezina contender from last year and a breakout tender.

I’d say if that top line goes cold, the team may be light on offense however you mix the lines up and spread the top line out could be very hard to handle. D is weak after the top pairing so despite the goaltender situation, with a weak D it’ll be hard to keep the puck out of your net and you’ll be winning games 5-4, 6-5, etc. you won’t see too many 2-1 games.
