If you were to put together a spreadsheet comparing Gallagher and his teammates when it comes to Corsi (CF%), Fenwick (FF%), shots for (SF%), scoring chances for (SCF%), scoring chances goals for (SCGF%), and high-danger scoring chances for (HDCF%), as this author did, and if you were to highlight the cells in yellow where those numbers were higher when Gallagher was on the ice with a given player, well, you'd see a lot of yellow. Only a handful of Habs in each category did not benefit from Gallagher's presence.
"I just like how he plays. He's so easy to read. He plays a north-south game like myself, he digs in the corners, goes to the net, he likes to go to the hard areas," described Paul Byron, Gallagher's linemate - along with Jonathan Drouin - for much of the final quarter of the regular season. "When you're on the ice with him, you know you're going to get chances, you know you're going to be battling, you know you're going to be around the net. I think we just compliment each other really well."
