For Frank Vatrano to be on the Vegas Golden Knights would make sense. He's a winger in his prime (29) and would be locked in for one more season after. He already has 20 goals this season and doesn't have a move clause, making him a nice target.
The Massachusetts native also has a tangy style on the power play. With seven power play goals this season (15th in the NHL), you can count on Vatrano adding some flavor to the Golden Knights if acquired.
