Sabres coach Ralph Krueger said he understood the penalty against Jokiharju, which came after the defenseman collided with Canucks forward Jake Virtanen as Eichel skated above them in the 3-on-3 extra period. Virtanen fell over Jokiharju's stick as he attempted to turn and switch onto Eichel.
The whistle sounded as Eichel skated alone to toward the right faceoff circle and buried a shot behind goaltender Thatcher Demko.
"I can understand the call because of it being literally a breakaway out of it," Krueger said. "It was definitely not intentional. Joki wasn't even looking in that direction, so in a normal moment of the game that might not get called. But I think in a 3-on-3 overtime when it leads to a breakaway, you can see both sides of it and you just have to swallow it down."
The Sabres erased deficits of 2-0, 3-2, and 5-3 in regulation. Okposo, Sam Reinhart, Victor Olofsson, Zemgus Girgensons, and Marcus Johansson all scored goals. Johansson's goal tied the score with 58.5 seconds remaining in the third period.
The Canucks came out strong to begin the contest, outshooting the Sabres 9-5 in the first period and taking an early lead on the first of Josh Leivo's two goals of the night. They went up 2-0 early in the second on a goal from Antoine Roussel, who also scored twice.
Though they had trouble solving the Canucks' pressure in the opening period, the Sabres responded quickly in the second. Within four minutes of Roussel's goal, Okposo and Reinhart both found the back of the net to tie the game at two goals apiece.
Leivo's second made it 3-2 later in the period, but Olofsson scored with a one-time shot on the power play to knot the score again heading into the intermission.
