When we started our journey we made a commitment to our fans to be relevant and to see the Chicago Blackhawks become the best professional hockey organization. There are not two finer symbols of that than Jonathan Toews and Patrick Kane. The commitment we have made to these incredible young men is equal to the commitment they have made to our team, our fans, our entire organization and the city of Chicago.
