Yeah, after the first two games Sutter has been a non-factor. That said turnovers are what have killed this team. Defensive zone turnovers. As far as Bylsma, he's rated high because players want to play for him, but the mistakes the past few games haven't been in regards to him, they've been really stupid passes. The "system" change worked like a charm against both PHI and NYR, and I didn't see that system when they had the lead. They're not very patient.
I think most teams are going to look wildly inconsistent for the first few weeks of the season due to the long layoff and short camp. The fact that only a couple Penguins played hockey elsewhere during the lockout probably doesn't help matters, either.
