Why do you guys suck this year

Coaching problems. Our goal since september = defensive team.(said by organization members,coaches,gm,players... ) Result = top5 worst defensive team in the NHL.
They said today before Islanders game. It will be a 1-0 type of game in pre-interviews.
Result:1-5 loss...
We just can't defend, other teams defend in the middle of the ice. We defend on the outside and we go forward instead going backwards. Watch a team like Arizona then watch Tampa. The difference = night and day.
Last year we didn't try to defend at all and every team just gave up the game vs tampa after a while = 62 wins super easy could have been 70 wins... in playoffs they didn't give up the game. Result = 0-4 sweep...

So when you have a coach who never focused on defense and tries it for the first time in his life to copy other teams. This is the result. Copycat stuff not always working....
So yeah, it's easy to say just give up instead of 20 danger chances/ night let's give up 15 only... Results sometimes: giving up 23 scoring chances... After sometime it will get better i'm sure, but until then we look like a bad team... It's a learning process, but i'm just not sure Cooper can just be a "Cooper 2.0" ever...

It's like in the NFL:
Bill Bellichick is the best coach, what he does: = focus only on defense. So if you go to him and say, let's focus on offense from 2021... the results would be: New England not winning any superbowls anymore...

It's hard to do a 360 degree turn and expect good results... Some night he goes back to same routines vs bad teams. Results: 9-3 win, 7-1 win... but those are meaningless games, when game is close, we just lose, because we just don't defend well enough, like 10-15 other teams can... St. Louis,Islanders,Boston,Washington,Carolina, etc...

TLDR:We need time!!! or new players/ new coaches to fix our internal system, which is imprinted in every players brain = full attack mode / zero defensive responsiblity. You need balance to win cups and we don't have that... right now... but it can change... but it's probably not in 2019/2020 season...
