There is a quick way to catch up on finding out just how amazing Chelios was.
If you never got to see Chelios play during his Hawks tenure (at the time, unless you had tickets to a home game, you saw him play on the road because Hawks home games were not on television unless it was a rare national TV home game), then you can always check out these highlight packages of the Hall of Fame defenseman...
Then you need to read CHGO's Chicago Blackhawks Podcast Host and beat writer Jay Zawaski's fantastic piece on Chelios' legacy.
Then finish up finding out about Chelios' greatness with the Athletic's Scott Powers and Mark Lazerus' collection of stories from Chris' teammates, family, and friends about what it was like to play with, against, or hang out with one of the greatest defensemen of all time.
Once you have done all that, hopefully, you have a true appreciation of what Chelios meant to the Blackhawks. For those that already knew, hopefully, you had a fond trip down memory lane.
