The Sabres are 0-15-3 since Feb. 23 and extended the NHL shootout-era record for the longest stretch without a victory. The shootout was implemented in the 2005-06 season, eliminating ties.
"Not really any words, to be honest," Sabres defenseman Brandon Montour said. "You go through a stretch like this, you can blame the system, blame coaches, blame other lines, you blame all those things, but I think in the end, you've got to be an NHL player. You go up 3-0 like that, especially as desperate as we are to just get two points, it's embarrassing.
"I know this whole stretch is embarrassing, but especially tonight, any team in the NHL, I don't care who you are, that's a win. Tough bounces, sure, here or there. … But the third period, you've just got to be desperate, and guys, I don't know if they try to feel sorry for each other, or, like, you just have to find a way there. That's unacceptable."
Provorov finished a 2-on-1 with Travis Konecny.
The Flyers forced overtime when Sean Couturier tied it 3-3 with 1:29 left in the third period and Brian Elliott pulled for the extra attacker.
"Honestly, I'm not sure why it keeps happening where we fall behind early, don't have a good start and only start playing when we're behind," said Provorov, who also had an assist. "I don't know, I guess maybe coming for the next game, coming out we should think that we're down 3-0 and maybe then we'll have a good start."
