This metric is measuring "grit" and grit always happens when the other team has the puck (except the rare case of hitting a guy while skating with the puck, like young Ovechkin used to do). So, the issue you have is not with this metric, but rather with "grit" itself. And that's silly issue, because what you are saying is essentially that it's useless to have ANY metric that is designed to measure what players are doing when the other team has the puck.
