The concern is that a defense that was overmatched by the Predators in the postseason has become even more inexperienced. Duncan Keith, Brent Seabrook and Michal Rozsival are the only returning defensemen who've won the Stanley Cup, and Rozsival, 38, isn't likely to play much. Chicago also lost defenseman Trevor van Riemsdyk who played 58 games last season but was selected by the Vegas Golden Knights in the NHL Expansion Draft.
At least three defense spots will be filled by players with a year or two of NHL experience, including Gustav Forsling and Michal Kempny.
Up front, the Blackhawks are counting on Saad reconnecting with center Jonathan Toews to form a potent top line with Richard Panik at right wing. Saad played in Chicago for four seasons, helping the Blackhawks win the Cup in 2013 and 2015, before he was traded to Columbus on June 30, 2015.
"I think we're a little bit similar in the way we play, with our style," Saad said of himself and Toews. "[He] can play off the rush, but he can protect the puck very well down low. That's something I think we did fairly well together, with puck possession [and] wearing teams down before making them pay."
The Blackhawks lost veteran right wing Marian Hossa, who announced June 21 he would miss the season with a progressive skin disorder that could end his career.
Looking to fill the void, Bowman signed free agent forwards Patrick Sharp, Tommy Wingels and Lance Bouma on July 1. Sharp played 10 seasons with Chicago (2005-15) and won the Cup three times. He had hip surgery March 28 that ended his season with the Dallas Stars.
"Physically, I feel great," he said. "It's been four months since the surgery to the hip, so I'm right on schedule. The season that I had last year, I don't think I've ever been as motivated to get back to the level I think I can play at."
