Hall, who played four seasons with the Devils from 2016-19, was traded to the Arizona Coyotes on Dec. 16, 2019. He signed a one-year contract with the Sabres on Oct. 11.
"He's such a play driver that he backs people off and he just opens the ice up," Sabres forward Eric Staal said of Hall. "He's got tremendous speed, power and obviously the respect around the League with his talent level and what he's done in the past that he's going to garner a little more attention and a little bit more time for his linemates."
Linus Ullmark made 31 saves and stopped all three shootout attempts. Staal, Tobias Rieder and Victor Olofsson scored for the Sabres (4-3-2), and Jack Eichel scored the only goal in the shootout.
"Definitely the character in the room and the language and calmness in our group, we're much, much calmer than last season with going up, going down, tie games," Buffalo coach Ralph Krueger said. "The language is good. It's good we have this adversity early already; it's making us more resilient for these kind of games and understanding that it's going to be like this every day. So I'm pleased with the effort."
Janne Kuokkanen scored his first NHL goal, and Scott Wedgewood made 28 saves for the Devils (3-3-2), who have lost three straight.
The teams play again here Sunday.
"You look at some of the big opportunities we had, great scoring opportunities," Devils coach Lindy Ruff said. "I look at the opportunity Jack [Hughes] had (one-timer saved by Ullmark in the third), we had a couple other ones around the net that we missed. The common theme through these first games has been we've missed too many good opportunities."
