We probably shouldn't think that this will continue, but it's certainly possible. Dunn got multiple PP tastes last year. Before Yeo, Pietrangelo was more of a PP2 guy to cut down on his workload. Maybe internally Dunn has been selected to be more useful on the PP than Parayko. An injury to one of the eight forwards getting power play time might shed more light. If Parayko doesn't get some daylight then, perhaps it's a sign.
