Still don't even know the opponent or who needs to be shutdown. Maybe the strategy isn't shutdown but 3 pairings that can move the puck in transition, to create offensive pressure, and maintain it with good rotation.
Lowry is the key player in any shutdown situation. I think Morrissey with Scheif is the most dangerous offensive pairing the Jets can have, but if you are playing 4 line, 3 pairing hockey it's hard to matchup line and pairings all the time. It's situational. Maybe you put Samberg and Melo in some tight spots together, if you want a more defensive looking pairing. That's probably your PK1.
