I just read on Twitter from multiple sources that Philly put in the biggest offers on both the big names so if it is strictly about money they will both be in the orange and black.
Philly has 3 big RFA forwards who will have to be signed in the summer of 2014. Giroux, Schenn and Couturier are only signed until next season and will be in line for big raises.
Voracek is an RFA this summer while Hartnel and Timmonen are UFAs next summer.
And to top it off they can't get rid of Pronger's massive contract (ends in the summer of 2017) because he signed after his 35th birthday and all signs are pointing towards his retirement.
Oh, and we have no idea what the cap will be when the new CBA is signed this summer/fall. The moment that CBA is signed the cap will likely fall (it's already climbed so high that the minimum cap number is now higher than the post-lockout maximum). The real shame is that the Blackhawks were able to so skillfully dump their terrible signings a few years ago (a lone to a European team here, trade to Florida there and poof their stupid FA choices were erased). GMs no longer seem to worry much about throwing contracts with huge term around. The best solution to this issue is for the minimum cap values to drop significantly so garbage teams don't take terrible contracts in trades just to reach the floor.
