Babcock blew his whistle and the players jumped into action, moving the puck from their zone, crossing center ice, dumping the puck in the offensive zone and going off for a line change. Over and over again, with Babcock pointing out the times he felt a group would have been called for too many men on the ice. After a few rotations in one direction, Babcock had them go the other way to simulate line changes in the second period.
It was jarring to see a collection of some of the world's greatest hockey players practicing something as second nature as changing lines, but it was a perfect example of the attention to detail Babcock and his coaching staff have brought to this training camp.
No stone will be left unturned this week.
"I thought what we were working on was our line change forecheck," Babcock said when asked why he was practicing line changes. "That's when you give up scoring chances. If you go through the game at the end each night, scoring chances, lots come off line changes. So we were trying not to give up a ton of territory on our line changes."
The first day of practice Monday was devoted to offensive-zone work, including entering the zone, cycling the puck and transitioning back toward the offensive zone. During every drill Babcock was shouting detailed instructions to individual players, where he should be on the ice in a given circumstance, what he should do with the puck.
