Level of pressure from opponents and number of teammates back are key factors.
In the season finale of Finding the Details with Laura Schuler, Laura breaks down defence partner support in terms of defensive breakout positioning.
"The type of support that you give to one another is really dependant on the situation," says Schuler. "I always tell our players, you gotta be constantly asking yourself 'what's the picture?' What's the picture in terms of the level of pressure that you're under... or what's the picture in terms of the numbers? How many forecheckers are they sending at you and how many players do you have back in the equation to help to be able to support that puck."
