From the Athletic :
Heading into their game against the Pittsburgh Penguins, the Sabres had won four of their last five games and finally had moved out of last place in the Eastern Conference. It was a chance to get their first three-game winning streak of the season and an opportunity for a four-point swing in the standings against a Penguins team that could be contending for a wild-card spot.
Instead, the Sabres got off to a slow start, managed the puck poorly, got lousy goaltending and ended up heading home from Pittsburgh with a 4-2 loss that put them right back in last place.
This was a winnable game that the Sabres made difficult due to self-inflicted mistakes.
