I think a lot of our struggles existing the zone are relating to the forwards positioning on our breakouts. Early in the year, I thought they were doing really well at supporting the d and we were breaking out much better, but it didn't seem to last.
Wrt playing guys too much, the Chychrun example happened in a game where Chabot, Zub, and Brannstrom were all out injured (not sure why but Mantiapolo missed pretty much the entire 2nd, and only played 3 shifts in the third), once Zub returned from injury he was down to 25 mins a night on the high end.
I really agree about giving up the blue line, but again, I think part of that (not all) is the forwards not providing enough back pressure, the result is often the opposition has a lot of speed going through the NZ making it much harder on the D to keep those tight gaps.
I want Capuano gone yesterday, but I think there's a lot more to our struggles than him.
