Saad scored 33 points (21 goals, 12 assists) in 58 regular-season games with Chicago last season and five points (two goals, three assists) in nine postseason games. The forward has scored at least 21 goals in five of the past six seasons, including an NHL career-high 31 with the Columbus Blue Jackets in 2015-16. He won the Stanley Cup with the Blackhawks in 2013 and 2015; after four seasons, they traded him to the Blue Jackets on June 30, 2015. He was traded back to the Blackhawks on June 23, 2017.
"We're extremely happy to have Brandon with us," Avalanche general manager Joe Sakic said. "He's a guy we've watched for years and we think he's going to be a great fit as one of our top six. We feel like we've solidified our top-six group, and also our bottom six, so we're pretty content with the depth we that have up front, for sure.
"He's a really good two-way player. He goes to the net, he gets his goals. We have a lot of great shooters, perimeter shooters, but he'll be getting to the net, getting those dirty goals. He's a versatile player, could play anywhere in the lineup, and we think it's going to be a great addition."
Saad, who has one season remaining on a six-year, $36 million contract he signed with Columbus on July 3, 2015, said he'd be open to discussing an extension with the Avalanche.
"I haven't really thought about it. It's a bit of a whirlwind dealing with selling the house in Chicago, moving the family and looking at real estate in Colorado," Saad said. "But Colorado's always been on my list as a team where I could see myself playing for a long time, with just the talent and a great hockey team. I hear great things about the city as well. I mean, like I said, it's early to tell, but definitely something I would look forward to playing [there] for a long time."
Saad said he believes that he's joining the Avalanche just as they are becoming a true Stanley Cup contender. Colorado lost in seven games to the Dallas Stars in the Western Conference Second Round of the Stanley Cup Playoffs last season.
"I know in Chicago, when we were winning, [the Avalanche] weren't at their peak, but they were a growing, good young hockey team," he said. "Now years later, it's a tough team to play against and a tough building to go into. It's kind of reverse effect. I'm happy to be a part of them at the peak now, playing with some great players and having a chance to win every year."
Zadorov, a 25-year-old defenseman, was a restricted free agent but signed his qualifying offer of $3.2 million before the trade. He scored 13 points (four goals, nine assists) in 64 regular-season games with Colorado last season and five points (three goals, two assists) in 15 postseason games. The 25-year-old ranked seventh in the NHL among defensemen with 175 hits.
