A former teammate of Weber in Nashville, Radulov last played in the League in 2011-12, when he had three goals and seven points in nine games with the Predators. He had one goal and six points in eight games in the 2012 Stanley Cup Playoffs, when he was suspended by the Predators for breaking curfew.
Radulov spent the past four seasons playing in the Kontinental Hockey League. He had 23 goals and 65 points in 53 games last season to help CSKA Moscow advance to the Gagarin Cup final.
Weber and CSKA GM Sergei Federov vouched for Radulov when Bergevin consulted with them prior to signing him to a one-year contract worth a reported $5.75 million on July 1.
"My scouts, we watched him a lot this year, he's one of the hardest-working kids, so we're taking a risk but hopefully the reward is big," Bergevin said.
The return of goalie Carey Price is expected to provide the Canadiens their biggest boost. Price was injured twice and missed most of last season -- he was 10-2-0 with a 2.06 goals-against average and .934 save percentate in 12 starts -- after winning the Hart and Vezina trophies in 2014-15. He was shut down for the season after spraining the medial collateral ligament in his right knee on Nov. 25.
Rookie Mike Condon shouldered the bulk of the goaltending in Price's absence and performed admirably, but he will have to battle Montoya for the backup role.
A return to full health by defenseman Jeff Petry, who had season-ending sports hernia surgery in March, and right wing Brendan Gallagher also should provide a boost, as will the addition of Shaw. A two-time Stanley Cup champion with Chicago, Shaw signed a six-year contract worth a reported $23.4 million with Montreal on June 27, three days after he was acquired from the Blackhawks for two second-round picks in the 2016 NHL Draft.
"I don't have to play against Shea Weber anymore, so that's a huge positive," Shaw said during a visit of the Canadiens practice facility on July 6. "We've had some good battles in front of the net, he actually broke one of my ribs, so I know he's a tough defenseman and he's going to be great for us. He's going to be that wall that stands in front of Carey and he's got that bomb from the point as well."
