Huh?
Example: Ehlers carries the puck into the zone, does two laps then turns it over up high by the blue line. Everyone on the Jets busts their asses to get back and they prevent the opposition from getting a shot off. The puck turns over and heads back up the ice and rhe Jets change
No shot attempt recorded but the stats don't reflect anything different from if Ehlers would have just cycled it down low instead of giving it away at blue line
BUT every Jet on the ice with Ehlers is pissed because they went from O zone time to busting their ass on a backcheck for no good reason
If no shot attempt was recorded then there is 1 less shot attempt recorded than there would have been if he had played it differently. And, in your example, the puck turned over and headed up the ice. Did the opposition get off a shot attempt? If not, there was 30 seconds of play with no SA by either side. That is a fact that shows up in the totals at the end of the game.
Does every Jet on the ice being pissed not affect their play which affects the total SA? What about the shot attempts they would have had if they had kept the puck in the O zone? Every single thing they do, or don't do, has some effect on the total shot attempts by both teams. If it doesn't lead to a SA by either team then it is the absence of a SA that could otherwise have been there. It is like that butterfly flapping its wings. Everything has a down stream effect.
