According to TSN, the Chicago BlackHawks acquired Kyle Calder from the Flyers for Lasse Kukkonen and a 3rd Pick (2007). They then traded Calder to Detroit for Jason Williams.
To CHICAGO: Jason Williams
To DETROIT: Kyle Calder
To PHILADELPHIA: Lasse Kukkonen + Chicago’s 3rd Pick (2007)
Great deal for the Hawks I’d say.
