I'm pretty confidant that any cap changes from what LeBrun's reporting will probably take effect at the end of next year.
see i dont think doing it that way is fair.. you could see teams that already have over next year's cap committed in salary.. i think it would have to be an across the board roll-back so that everyone keeps relatively the same cap space.. otherwise you could end up seeing next summer's UFA's being left unsigned because so many teams are already up against the cap or already over it
