Konsta Helenius#94
C with Buffalo, 2025–26
On-ice PDO 1.000 (5v5 on-ice shooting plus save percentage). PDO over one season is noisy, it regresses hard toward 1.000, so read it as recent puck luck rather than a skill.
Buffalo's 5v5 xGF% rose most with Benson (+36.3) and fell most with Doan (-36.6).

With or Without You
Buffalo's 5v5 shot-attempt (CF%) and expected-goal (xGF%) share with Helenius on the ice, split by whether each teammate was out there too. Δ is the with-minus-apart gap: a positive number means the pair drove play better together than Helenius did without that teammate. That gap is always measured from the named player's side, so the same pair can read positive on one player's table and negative on the other's. 2025–26 regular season, minimum 20:00 together. Together counts every 5v5 second the two share, whoever else is on the ice, so a pair's time and xGF% here differ slightly from the Line Combinations table, which counts only the seconds that exact pair or trio was the unit.

Shift Rhythm Profile
How Helenius's shift length lines up with on-ice results, 2025–26 regular season. A shift under 0:30 is a quick change, usually right off a whistle. 0:30 to 0:45 is a short shift and 0:45 to 1:00 a typical one. 1:00 or more is a long shift, more likely during a delayed line change, a d-zone lockdown, or a penalty kill that ran long. Shift length is an outcome before it is a cause: a shift runs long because the unit could not change. Most of a long shift is ordinary play, though; the stretch past the one-minute mark is where a unit is really pinned, and each game page counts that time on its own. Empty-net goals against are left out.
29 of 34 of Helenius's shifts over a minute were hemmed-in shifts (mostly even strength, more than 60 seconds of unbroken play).
