I think I'm beginning to see why AV can build a really good team, but hasn't been able to win the Cup. The challenges are a fluke occurrence, but his personnel decisions are a bit too conservative. From a player standpoint, his desire for robotic monotony of every line is why the Flyers are struggling to score. Braun, Grant, Thompson... robotic. Ghost, Frost... dynamic.
System wise, there were 3 instances last night where the Flyers lost an offensive zone face-off and the center who lost the draw moved forward to pressure the puck carrier and the wingers and d-men retreated to the neutral zone. If that's not conservative, I don't know what is. Certainly don't see the Islanders, or Montreal in the previous series, backing off and allowing the Flyers a free exit of the defensive end. It's not as if the Isles even had possession moving up ice. It was IMMEDIATELY off the face-off draw. That's a coach directive, and if it applies on a face-off, it applies to other situations as well - which we painfully see. Especially when they get a lead.
From what I've seen of this team all year, their best use of speed is pinning opposing teams down in their own end with the forecheck. Not allowing other teams to get speed up through the NZ. That is when the Flyers are at their best, and so far in these playoffs I've seen a team conservatively retreating instead of aggressively pressuring.
I think that falls on AV, and it's why if not for Carter Hart, the Flyers would've been bounced in round 1.
