After the 1983 finals, when the Islanders swept the Oilers, they made this observation:
"After game four, the Oilers players walked past the Islanders' dressing room and noticed many of the Islanders players exhausted and covered in ice packs rather than wildly celebrating, with
Wayne Gretzky suggesting that this gave the Oilers inspiration that they needed in order to win next year."
Should note those Islanders (with Potvin, Trottier, Bossy and Gillies) were seen as playoff chokes before winning the Cup in 1980. The big change there was going to Billy Smith instead of Chico Resch in the playoffs.
So don't let the Leafs find the right goalie and don't let them see the other team's locker room after they lose in the playoffs again.
