The puck was just dumped in. He won his engagement fairly clean with Vrana, so it's not one of those scenarios where one guy is pushing him into the trolley tracks. He has body position, the puck is on his side and he's beginning to try to play it.
In that moment, something should be screaming at you that there's at least one more Capital coming with speed. F2 isn't on the scene yet, he has dump in speed, and you just won the puck almost too easily from the guy you would have tied up on the wall. Get your head up, and get ready to eat that puck and trap it against the wall again, because unless you come away from Vrana with the puck glued to your stick and an outlet pass in mind you just don't have the time to do everything you're trying to get done.
the Capitals, fairly, didn't give him enough time to play the puck and that's completely allowed. He made the wrong decision. If he were a quarterback, he tried to make a completion instead of throwing the ball away.
