Ok Boston has more NBA history than Memphis, but... does Gasol want to be in a team under construction? this year's season is lost, and he wants a team to be a lock in playoffs! Chicago from my point of view is the one thar has all Memphis wants: 2007 lottery picks (knicks), expiring contracts (Brown, Sweetney...) and rising stars such as Deng and Gordon.
Maybe Brown, Allen and Deng shoud be enough for Gasol or maybe Brown, Allen, Sweetney + Knicks 2007 pick. Salaries match in both options!
Anyway I understand Boston is a them where everybody would like to play because of his history.
