The fact that Murphy runs Kitchener's PP and Spott is very familiar with him could lead to two things imo
1. Put Murphy with Hamilton
2. Put Murphy with any random Dman, and let him run the 2nd PP unit
A forward or a defensemen like Harrington/Reinhart will probably play with Murphy on the first powerplay unit and Rielly will be with Murphy on another PP unit. Expect there to be 3 powerplay units, one that's "Murphys", one where Murphy shares it with Rielly or Hamilton, and one that's Rielly-Hamilton.
