how do they know when to change lines? how long are shifts usually?
They donāt always know. THis is always a hard question to answer for me because like, itās kind of anti-climactic. They just...do it. Like there are some players with specifi roles and they know exactly how long tehy need to be out and in what situations. In the bruins/leafs series Patrice Bergeron, Zdeno Chara, and Charlie McAvoy jump onto the ice every single time Auston Matthews does. But matchups are a little bit different than line changes.Ā
So letās say, how does a player know to change against an okay team, during a meaningless game, and itās 5 minutes into the second and the team is up 3-1. At this point, people kind of admit to not knowing. They kind of go until something else on the ice suggests they should come off. Shifts are typically 30-60 seconds. 30 seconds is around where a fourth line winger would go and 60 seconds is about where your top d man goes. But thatās average, some shifts can go up to 2 minutes like how the leafs have ron hainsey play fullĀ penalty kills. so guys will generally, know what that feels like, theyāll know who theyāre supposed to be on the ice with, and they know the rules of the game. So like a player isnāt going to go for a line change after he ices the puck. But if the other team ices the puck they may need to ask their coach or at least look towards the bench.Ā
Line changes are less about calling a line off and more about arranging which players are supposed to be on the ice. For instance, if youāre the centre and youāre not looking towards the bench. But your winger decides itās a good tiem to get off the ice you may realize itās time for a change when you see that you have a different lines winger out there with you. It just isnāt always a good time to change lines. You generally want to change lines when possession changes zones and you want to do it in a staggered fashion with the d men. So you want to dump the puck towards a d man and then get off the ice. This would allow your team to remain in possession and for your forward line to get off the ice while the d waits for their players to come back out on the ice. Or youāre just skating by the bench through the neutral zone and as one player hops off another hops on.Ā
But if there was any science to line changes, there probably wouldnāt be too many men penalties.
