Iafallo had a strong defensive game and scored in overtime in Los Angeles' 4-3 win in Game 1 of the Western Conference First Round against the Edmonton Oilers at Rogers Place on Monday.
"Alex is kind of our unsung hero," Kings coach Todd McLellan said. "He cleans up a lot of messes, errors, mistakes, for teammates. He seems to be the clean-up guy. But on the other side of it, he has the ability to score. He can go up and down the lineup, he penalty kills, he blocks shots, is a utility guy that is often forgotten when you roll into Calgary or Edmonton, or wherever we might be going. He certainly is not forgotten in our locker room."
Iafallo scored on the power play at 9:19 of overtime, taking a pass from Viktor Arvidsson in the slot and one-timing a shot past Oilers goalie Stuart Skinner.

Game 2 is at Rogers Place on Wednesday (10 p.m. ET; ESPN, CBC, TVAS, SN, BSSC).
"I was just trying to get lost," Iafallo said. "We have a lot of good players that can make good passes. I was just in the middle there and trying to find a good spot. [Anze Kopitar] had it on the wall and got it down to 'Arvi' and I was just trying to get in a good spot past the defenseman. He was able to make that pass to me and I just hammered it home."
The Kings overcame a two-goal, third-period deficit twice in the victory. Adrian Kempe scored two goals and Kopitar had four points (one goal, three assists). The Kings were able to keep Oilers captain Connor McDavid off the score sheet, holding him to five shots on goal. McDavid led the NHL with 153 points (64 goals, 89 assists) during the regular season, including a season-ending 16-game point streak (10 goals, 19 assists).
