It's hard to have a rational discussion about that on this board. You have a vocal few who inexplicably seem to believe Quick is falling apart. And then then you have the majority which freaks the hell out at that and claims almost every goal he let's in was the fault of someone else.
The reality is somewhere in the middle there. With better D, yes, obviously Quick's save pct would go up. But he's also struggling. That's plain. He's not making that big save when the team needs it sometimes, and that's cost the team points.
No, he's not awful. But guys like Lundqvist and Price have carried terrible Ds, so I dunno. Quick is definitely not chasing a Vezina this year.
