Mattias Samuelsson

Marty corners Buffalo's Mattias Samuelsson in the latest edition of his no-holds-barred sit-downs that cut straight to the heart of a player's game. Defensemen like Samuelsson rarely spill this much on their nightly battles and what keeps them sharp amid the grind. Insiders tune in for these chats because they reveal the edge that separates good from elite on the blue line.

Florida Panthers goaltender Daniil Tarasov unleashes on the league's Situation Room after they let a disputed third-period goal stand in a tight 3-2 loss to Buffalo. With the game knotted at one, Sabres forward Beck Malenstyn's long shot squeaks past Tarasov's glove only after Mattias Samuelsson's stick jams it, yet Toronto rules the contact incidental and allows it.

Blues netminder Jordan Binnington and blueliner Colton Parayko gear up for a golden showdown at the Olympics, bringing St. Louis grit to the international stage. These two know pressure from playoff runs, and now they chase hardware with their countries on the line. The stakes skyrocket as familiar foes collide for the top prize.

The Buffalo Sabres sit pretty in the East's first wild-card spot, chasing their first playoffs since 2011, and GM Jarmo Kekalainen eyes Winnipeg's Logan Stanley to shore up that shaky third pairing. Stanley brings the exact grit and size Buffalo craves behind their offensive top-four of Dahlin, Byram, Samuelsson, and Power, all at a bargain $1.25 million cap hit as he heads to UFA status.

The Sabres sit atop the East after their hot streak, but that three-game skid before the Olympic break exposed a glaring hole on the blue line where only Dahlin, Power, Samuelsson, and Byram carry the load. GM Jarmo Kekalainen holds steady through the roster freeze, yet whispers from Elliotte Friedman point to a "beefier blueliner" topping his shopping list once trading resumes ahead of the March 6 deadline.
