Matthew beams when asked about that aspect of his brother's elite skill-set.
"It makes me very proud," he said. "His competitiveness on the ice, it's very infectious with the way he plays. … We're not necessarily in similar situations, but for the both of us, that third year, we probably took another step.
"I know times have been tough for them this year, but he's done a great job of leading them. We all see the way he plays, the way he carries himself - he's the epitome of a leader in that dressing room. Just an all-around great guy, great player and I'm happy to see the notoriety he's getting this year, because he deserves it.
"Just very proud of what he's done so far.
"We're going to have our hands full tonight with the way he's playing, the way his line is playing. ... In talking to him, his team gets a little more fired up to play us, because they want to win it for him, too. We've got to be ready, because we're going to get their best tonight."
And that, at the heart of it, is what this 'rivalry' is all about.
While there's no doubt these two have had tonight circled on their calendars for some time, it's only the first of four straight, five of the next six, and nine overall against each other this year.
The Flames are trying to steady the ship after a turbulent week, but earned three of a possible four points during a two-game set in Toronto. The Sens, meanwhile, are winners of two straight and have played better all month, but are so far in arrears, the playoff cut line may as well be the summit of Kilimanjaro.
That said, there no bad teams in this division. The Sens are a young group that plays hard, and has a number of key pieces that could make this club a great one soon - and for a long, long time.
The Flames aren't taking them lightly.
"I don't think we played nearly the game we wanted to play yesterday," Matthew said. "With saying that, we had a chance to win with three-and-a-half (minutes) left.
"Yesterday, they took it to us pretty good and we were defending pretty much all game. We've got to support it a bit better and watching (Ottawa's) games, they're playing hard, they're playing fast, they're playing with the puck and playing physical."
