Kane was named one the 100 Greatest Players in NHL history during the League's Centennial celebration in 2017.
"I still think I have the ability to elevate my game at the most important times," he said after last season ended. "I've always been able to do that throughout my career, and I still think that's something that lives within me."
Chicago opens the season at the Vegas Golden Knights on Sept. 29 (10:30 p.m. ET) as part of a season-opening triple header on ESPN.
On Monday, two days after signing a five-year, $75 million contract with Chicago, center Connor Bedard said Kane returning to the Blackhawks would be great for him and the entire organization, particularly regarding the atmosphere for Chicago's home opener against the St. Louis Blues on Oct. 6.
"I can't imagine his first game back at the (United Center with the Blackhawks), the reaction he'd get and how much juice that would bring to not only our team but our fans, as well," said Bedard, who is expected to be out until November because of left shoulder surgery. "That would be incredible to play with him and learn from him.
"You talk about the legacy aspect of it, but just as a team, he would make us a way better team. He's still an amazing player. ... He still has some good gas left in him. I think he has 2-3 years left in him."
Kane's first game against the Red Wings this season will be at Little Caesars Arena on Oct. 29.
Last week, Blackhawks ambassador and former Chicago defenseman Chris Chelios gave 104.3 The Score in Chicago his view of what Kane means to the team and the city.
"You saw the reception (Kane) got a couple of years ago during the jersey retirement," Chelios said. "He still belongs in Chicago."
