"From where I was at my peak to where I am now, there's a difference in my game," Bickell told NHL.com. "I don't think I will ever get back to that point with the circumstances. For the last couple months, from where I was mentally and physically to where I am now, it's a big change. I'm just happy to finish up here and move on."
Hurricanes coach Bill Peters was emotional when asked about the 31-year-old Bickell after the morning skate on Saturday.
"He's a man's man and he's a pro's pro, and he's unbelievably brave," Peters said of Bickell, whom he coached for two seasons with Rockford of the AHL.
Bickell was selected by Chicago in the second round (41st overall) of the 2004 NHL draft. He owns 136 points (66 goals, 70 assists) in 393 NHL career regular-season games with the Blackhawks and Hurricanes.
