That’s a lot of questions. Bear with me.
The receivers decide how good a play the puck carrier will make, frequently. Are they working to use speed and get available? A lot of times they make the D-D pass inevitable.
You have to work to be available and be a receiver.
Play slows down when receivers aren’t committed to getting available.
Obviously, the D have to be quick , also, in recovering and reading.
A good player is able to make good reads approaching the opposition BL on the rush....can I skate it in and maintain possession?....make a play( pass) to a teammate and maintain puck possession with speed ? Or chip to a place where a teammate or I can retain or regain possession.?
Individual confidence, IQ, skill and ability , not primarily coaching, IMO, decide the decision more times than not . A BL turnover can lead to countering an odd man rush against... Those can be trouble.
On the positive side, the right decision can lead to a quality scoring chance for..
I can guarantee there a very few to zero restrictions re when the Flames have the puck.
Players are playing in the NHL because they make good decisions .
Coaches are responsible for explaining what they should expect from the opposition.
The more times you make smart decisions the more confidence you acquire. Also , the harder you work to GET available, the easier decision you make re execution for yourself and/ or your teammate.
The players are responsible for making a lot more good decisions than mediocre or bad ones. Too many of the latter, you watch. Rightly so..
Confidence is tough to acquire...easy to lose. You build layers of confidence by doing things right. The more layers you have, the tougher it is to lose.
Are their defensive systems ?
For sure.
Go back to the offensive concepts and principles...as well as individual and team tactics.
Reverse them and you have the defensive side of it...
Limit time and/or space, protect mid ice corridor, D side positioning...etc.
I want to concentrate on the game.
Answered the best I could.
