Patrick Kane spent much of his career cycling through linemates, a new center or a new left wing showing up on a nearly nightly basis. He broke into the league alongside Jonathan Toews, fared well with Patrick Sharp, won a Stanley Cup with Michal Handzus, went on a tear with Kris Versteeg and Brad Richards and got a spin with nearly every forward in the Blackhawks’ system from 2012 to 2015. Then Artemi Panarin showed up, and the revolving door stopped spinning. So while Kane is close friends with Brandon Saad and understands the reasoning behind the trade that sent Panarin to the Blue Jackets and brought Saad back to Chicago, he wasn’t exactly happy about it. ‘‘I’d be lying to you if I was sitting up here saying I wasn’t disappointed when it first went down, no doubt about it,’’ Kane said at the 10th annual Hawks convention at the downtown Hilton. ‘‘Artemi’s a great kid, someone I got along with really well off the ice and had that chemistry with on the ice. It was just fun to play with him every night. I’ll miss him, for sure.’’ Kane had his two most productive seasons with Panarin by his side. He won the Hart Trophy and the scoring title in 2015-16, breaking the 100-point barrier for the first time, then posted 89 points last season. But he didn’t win the Stanley Cup in those two seasons, and Panarin was a victim of general manager Stan Bowman’s offseason overhaul that sought to make the Hawks a little bigger, a little faster and a lot harder to play against.
