Chicago defenseman Brent Seabrook said Shaw's energy off the ice is just as vital.
"You need those guys around to spark things," Seabrook said. "The season gets long, gets dragged out, you're in some dark cities, snow and weather and all that kind of stuff, and then a guy like [Shaw] really brings that energy, that fire. Those tough days, long trips, things like that, he always seems to bring that energy and emotion and makes the team better."
Shaw had 96 points (41 goals, 55 assists) in three seasons with the Canadiens, including an NHL career-high 47 (19 goals, 28 assists) in 63 games last season. He also finished the season healthy, a positive after he had surgery on his left knee April 25, 2018.
"You look at his year, last year, he scored [nearly] 50 points, almost 20 goals, so his game's getting better and better," Blackhawks forward Patrick Kane said. "He's probably better than the last time he was here in Chicago. I'm sure he's looking for a bigger role, and he'll definitely be able to help us out. I'm happy to have him on our side again."
Shaw said he loved his time in Montreal but always hoped he'd get another chance with Chicago, where he had 137 points (70 goals, 67 assists) in 322 regular-season games and 35 points (16 goals,19 assists) in 67 Stanley Cup Playoff games from 2011-16.
"I feel I still have a lot to give," Shaw said. "I came off a pretty good year and I'm excited, feeling healthy, feeling energized. To come back to a city that's given me so much love and helped me grow to who I am, I have nothing but smiles."
