What's also clear is that the Sabres appear to have found a promising presence in goal. Rookie Devon Levi made his fifth-straight start and made 24 saves.
"I think he is a player and a person that will take from any experience and maximize what you can take from it," Granato said. "I thought he was solid today from the standpoint of focus, from the standpoint of resilience and that's good."
The Sabres had the misfortune of digging themselves a 2-0 hole on goals by Jesper Boqvist and Jonas Siegenthaler. New Jersey successfully challenged an offsides call that wiped out a goal by JJ Peterka that would have cut the deficit in half in the second period before Jeff Skinner finally put the Sabres on the board.
The Sabres outshot the Devils 15-9 in the second period and led New Jersey in 5-on-5 high-danger scoring chances by a 7-4 margin, according to Natural Stat Trick.
"We had plenty of chances to convert, and enough to win," Granato said. "That game, at the end of the second we could've been up 3-1 instead of down 3-1, is the way we felt."
Miles Wood restored the Devils' two-goal lead and Tomas Tatar tallied 7:10 into the third period to put the Sabres behind 4-1, but Mattias Samuelsson kept Buffalo within striking distance with his second goal of the season at 13:55.
New Jersey added a pair of empty netters late to seal the Sabres fate.
"We don't have a lot of experience, so going through this experience, you have to unfortunately soak up the negative," Granato said. "A lot of things in life are learned through negative. Unfortunately, it's just the way people grow."
