Forward Adam Erne flicks the puck into the net, but he has no time to celebrate.
He flips around. Crunch, crunch, crunch. Snow flies off his skates. Erne then squares his body as he arrives in the defensive zone, steps away from the net.
Within a second, a puck rockets through the air. Erne steps in front before it can reach the goaltender. The puck ricochets off Erne's shin.
No goal. Erne has successfully completed the drill and is done with it for a minute or two. At least until he goes again.
It's a drill that the Lightning runs many times during practice as players have to hustle the length of the ice to make a play, testing their speed and endurance.
