King said Vlasic was probably the Blackhawks' best defenseman against Arizona but is still finding his way in the NHL.
"I was happy for the kid," King said. "But he's got to learn to defend. You can't just be all offense."
Smith cut the lead to 3-2 at 9:42 of the third period, scoring from one knee off Kessel's pass, and Anton Stralman tied it 3-3 at 13:43 with a shot that went top shelf.
"I think maybe we get away from our game a little bit, try to maybe put more up on the board," DeBrincat said. "When we have a lead, we just need to play some defense, not turn the puck over."
