The system doesn't eliminate anything. The terrible PK + useless bottom 6ers + Seidenberg is what is making it appear as bad team defense.
Re: short leashes....Ya I know and i agree. Short leashes on Ho-Sang & Pulock = long leashes on Chimera & Seidenberg. Its a problem. But this isn't new.
As per regularly giving up the 6 goals...as mentioned earlier, I think it has more to do with the terrible PK, mediocre goaltending and lack of quality depth that have more to with it than 'the system'.
Yes 'the system' is more open than others we've seen...but imo there are way bigger problems (mentioned above) that are causing the goals against.
The system is very reliant on impeccable transition which we fail at miserably because it would require every player on the team to have Leddy like speed... we crash with many forwards and with one bad pass or one chipped puck the other team is on a breakaway.
We give up first goals all the time.. that is a lot on on the coach, not preparing his team.
Teams devour us the 2nd time they play us, and yet we can't find a way to catch up to that team... (e.g. Dallas, CBJ Colorado)... our coaching can't adjust
We are bad on the road, which means Doug Weight's biggest advantage is being able to match up lines at home.
Seidenberg has a short leash, he doesn't play much at all
Chimera is not part of the problem, he hits people at least, he will start a fight to get us going, he kills penalties... I just don't like his dumb penalties which has reduced lately
PK is bad, but we give up more goals on odd man rushes and forwards out of position not covering, way too many open forwards... I don't love Halak, but most goalies aren't making those saves, he has cut down on soft goals.
Our bottom 6ers are not used with a purpose, you change the lines up every game, no chemistry is built, expectation on the 3rd line is to be like the 2nd line, Beau/Quine/JHS/Bernier/Nelson/Prince, all struggle because of identity role issues. They all seem like they are playing a pickup hockey game with strangers.
The 6 goals a game, a lot happens with the JT line on the ice, Lee for all the goals he scores.. is the worst defensive forward they have had in a long time... how many RW's are uncontested getting 2-3 whacks at the puck.
Biggest issue for goals against is becoming more a matter of forwards not getting back on time.... that only started in the Weight regime.. Under Cappy, only Chimera did that.
