Some things to consider: if you get Kane, then there is no JVR for Luke Schenn trade...
Also, assuming Holmgren still felt he needed to clean house/Pronger & Laviolette are in his ear telling him Richards and Carter aren't leaders, and wants to get bigger on the wings, do they still make those same exact trades? With Giroux, Briere, and Kane, they'd be pretty small. Maybe there's no Couturier, Voracek, Simmonds, B. Schenn. Maybe they do. Maybe there isn't enough room to sign Jagr and Giroux and Voracek don't get the same kind of mentoring and don't make the same progressions..
