DeBoer, who took the upstart New Jersey Devils on a surprising run to the Stanley Cup Final in 2012, against the Kings, has preached the same lesson to his group from the first day.
"We tried to lay a foundation in training camp for this time of year so that we would be able to withstand the highs and the lows and the ups and the downs and keep relying on that [foundation] and that is what we are doing," DeBoer said.
There weren't higher highs or lower lows than during a wild third period in Game 4. The Sharks took a 3-0 lead early in the period and the party had begun in earnest in the SAP Center stands.
Less than five minutes later, the Sharks were hanging on for dear life after the Kings scored two goals.
But the Sharks handled the biggest push of the series from the Kings. San Jose may have played the majority of the final 10 minutes in their end, but they did not get rattled and they did not allow the tying goal.
"When it was 3-2 for a while last night, I felt calm and the guys seemed like they were calm and, even if everyone else in the building was nervous, it was a lot of fun," said Sharks defenseman Marc-Edouard Vlasic, who had two blocked shots in the final minute. "I didn't expect anything less than a close game."
