Shaq is looking for the $, and a ring would be nice too, but he knows he's in the twilight of his NBA carreer and is willing to go to whoever will take him.
Boston gets to sell jerseys and get butts in the seats (not that has been an issue, but, surely they recognize whats going on in Miami and Orlando). They should recognize that their run is close to being over.
Shaq gets a check, gets to play with some HOFers, and is allowed to have awesome press conferences.
Its win/win.
Still, I find it sad that some guys cant bow out when its their time. See Emmitt Smith in a Cards jersey for an example.
