Corey Crawford shared the William M. Jennings Trophy with Ray Emery in the 2012-2013 season. The Jennings Trophy is awarded to the goaltender(s) who allow the fewest goals against during the regular season. Crawford and Emery were both goaltenders for the Chicago Blackhawks that season, and they combined to allow only 102 goals in 48 games, the fewest in the NHL.
