The Sabres conclude their busy week having taken six of an available 14 points (2-1-2). Krueger had said prior to the game that he felt they were beginning to find consistency in their defensive identity, a trend that continued Saturday.
The one area still in need of a momentum shift is the power play, which remained cold during a 0-for-2 night. The Maple Leafs, meanwhile, scored their lone goal in regulation on a power play during the second period, a backhand off the stick of William Nylander.
"It definitely gets in your head a little bit but you can't dwell on it," alternate captain Marcus Johansson said. "You've just got to go out and execute it. We've got to work on it, we've got to stick with it. Like I said, we just put this group together. We've just got to figure it out together."
The Sabres get a day of rest Sunday. They then begin another busy stretch of four games in seven days, including a three-game swing through Western Canada.
They'll go into it with plenty to build on.
"We're really pleased with the way the team is settling into a pretty consistent game here that gives us a chance every night," Krueger said. "We've been involved in excellent games against some of the strongest teams in the National Hockey League.
"It's about having that mental strength now to take that into every game we play and just continue to build forward. But we feel to be in a good place, guys feel confident. We really showed it here in Toronto today coming off this back-to-back and being the better team down the stretch today."
