Nick Leddy - 9PPP, 2:16 PPTOI (5 games left, 2vs NJ, 2 vs BUF and 1 vs BOS)
Mark Giordano - 7PPP, 2:14 PPTOI (6 games left, 4 vs VAN)
Seth Jones - 7PPP, 2:01 PPTOI (4 games left)
Devon Toews - 6PPP, 1:43 PPTOI (7 games left, 4 vs LA, 2 vs SJ and 1 vs Vegas)
Faulk and Reilly don't get enough PP time IMO. So a quick look above says Leddy/Gio/Toews. I would take Leddy. Although I think Toews is intriguing but most of his PP time is 2nd unit. Gio hasn't done much in his last 7 game (1 point). CGY is done so Valimaki might get some PP time. Good luck.
