The unusual messaging following Islanders into season comes with giant caveat

TORONTO — It’s easy to exercise cautious optimism after everything goes right in training camp.It’s harder to strike an appropriate tone when the last few days of preseason were rough enough that people in the organization started to feel uneasy. “I will tell you, when I come into teams, it doesn’t happen immediately and it takes a while,” Islanders coach Pete DeBoer said Saturday night.

And we’ve gotta be patient.” This is not something you usually hear after a preseason game. The giant caveat to everything — which doubles as another reason that training camp was less than ideal — is that Wednesday’s opener against Gavin McKenna and the Maple Leafs will be the first time the Islanders NHL lineup is all on the ice together. That was supposed to be the case Saturday against the Devils, but the vagaries of preseason roster rules combined with understandable caution meant that Matthew Schaefer, Brayden Schenn and Tony DeAngelo were all held out of the 4-1 loss.Logan Stanley, who will line up next to DeAngelo on the third pair Wednesday, was signed the next day.
