Matthews and Hyman have been together since the start of the season. Brown initially played with them primarily on the road for defensive purposes, replacing William Nylander, who would play with Nazem Kadri and Leo Komarov. However, he's been a full-time member of the line for the past nine games and the results have been excellent.
Toronto is 6-2-1 in those nine games. Matthews, Brown and Hyman have combined for 12 goals and 29 points, including seven goals and 12 points for Matthews and five goals and nine points for Brown. Hyman has eight points, all assists.
The Maple Leafs, who haven't played since Saturday, visit the New York Rangers at Madison Square Garden on Friday (7 p.m. ET; MSG, TSN4, NHL.TV).
"We enjoy playing with each other," Matthews said. "Over the last couple of weeks we've definitely gelled more and more and found each other, a bit more chemistry."
How? Why?
It starts with Hyman, arguably the Maple Leafs' most aggressive forechecker, winning the puck back in 50-50 battles.
"I think nine times out of 10, he's come away with the puck in the corners," Matthews said. "It's just knowing where he wants to throw the puck and trying to get open for him because you know he's coming out with it most of the time."
Ideally, Brown gets the puck from Hyman first, because he's the distributor and Matthews is the shooter. Brown has a great shot as well, but he defers to Matthews if he has the shot.
"He's a shooter, absolutely," Brown said. "We get him the puck in different ways. I'm a bit more of a passer and Zach goes and gets pucks, he's a hunter. A 2-on-1, you'd like to think Auston is shooting it because it's a tough shot to stop."
And where is Hyman in all of this?
"He gets to the netfront for those guys, takes the 'D' away," Maple Leafs coach Mike Babcock said.
