"It was a heck of an effort to get the tying one and then we had some poor board work again (on the overtime goal).
"So [goals] one and four, poor board work, they step inside us and it's in the net."
Caggiula, who was in the running to be a hero in Game 4 for the Oilers, said that he and his teammates are discovering that quick adaptability to the wild swings of emotion and transition from good to bad is a must in the playoffs.
"Momentum can change at any given point in time," Caggiula said. "It's one simple play that can change the whole momentum of the game. We've figured out that momentum doesn't carry from game to game necessarily. We'll have a fresh start for Game 5 in Anaheim and it's a 2-2 series.
"We're doing just fine. We were in this situation before and we know how to handle it."
Caggiula insisted that the Oilers are gaining confidence in their ability to process it all, especially the setbacks.
"We're a resilient group," he said. "We're young and we're hungry. We kind of shot ourselves in the foot again in the second period but to come back like we did, it shows how resilient we are. We just have to play a full 60 minutes and not dig ourselves a hole."
With a 2-0 series lead gone, and wasted positives or not, McDavid refused to show any disappointment heading into Game 5 on Friday.
"We were in this same position last series, tied 2-2 (against the San Jose Sharks)," he said. "We're going into a building where we have had success before. We're comfortable playing there. You never want to play a series where you lose both at home, but that is the case that both teams find themselves in. Now it's a race to two."
