I think the comparisons to the Devils in the 90's isn't really an indictment of the Flyers as playing that way, but rather the result of BOTH teams with very similar gameplans. Both teams are playing an aggressive 1-2-2 and/or 2-1-2, even if all 5 players are deep in the offensive forecheck when doing so. Defensively, both teams are allowing perimeter possession and locking down the middle. Through the NZ, forget about it. There's just nothing there.
The end result is a game with very little breathing room for either side with a lot of blue line turnovers to the point where I feel like I'm constantly looking at the center ice logo and the two "Stanley Cup" logos under the ice at each blue line.
I suspect should the Flyers move on, we'll see a completely different game. I expected this against Montreal, and it's really their only way to win. They're quick, tenacious, and well coached. I'll be happy to see the Flyers put them in the rear view mirror.
