So, let's make these clear.
We are not loosing cap flexibility (we will have none in any case).
We are not loosing money (not that I care about fat **** Dolan, but he'd actually make money)
We are not ruining the roster (we keeping an, at least, capable, productive player)
We might actually be adding a valuable asset (see [Only registered and activated users can see links. ])
So what were the reasons not to re-sign Jeremy Lin again?
