Still, two defeats after four straight wins put the team in an uncomfortable spot, and a five-day break between games allowed players and coaches to evaluate what changed.
While the practices touched on a bit of everything, the focus of Monday's session gave a clear indication of what problem coach John Hynes saw in the Devils' play.
"Our first practice was a lot of battle drills," forward Taylor Hall said.
