Yes Lehkonen acquired the goal in the Av end in during the shift, couldn’t see which Av was departing the ice at the Blue line far side as Kadri received the pass on the other side of the Tampa Blue line.
No Lightning players were covering the departing Av at the boards.
Kadri splits and beats two defensemen shoots and pirouettes on one leg avoiding contact with Vasilevsky in the goal crease. Puck rises between right arm and body through a “wicket pit” under the pipe and lodges high in the the net.
It should be noted that 2 Lightning players were still exiting on the shift change when Nazem received the perfect assist pass from Lehkonen and then scored in a bang bang speed. The departing Av back was to the action and was never involved in the play after Colorado gained control of the puck at the other end in the opposite circle.
