I'm not sure if it was a set play or not, but if you watch Perron's goal again either A) Berg missed the pass from Gaber in the slot, or B) He purposely let the puck go by to Perron on his off wing for the clapper.
If it's B then that's a great hockey play getting all eyes on Berg in the middle for Perron to find space. If it's A, then still a play we will remember with Perron getting his first.
