First of all, they have to cut Zeller. And they haven't done it yet. Most see him as an albatross, but he does have ties with Stevens from Indiana which I suspect has been keeping him around.
They are quietly stocking up on 4s--Tatum, Zizic and Theis. I guess this is their answer to upgrading their rebounding and toughness up front. You can't rule out any deals-- I don't know how Aldridge fits.
I wonder if the two star addition was ever in their plans. Maybe they just wanted one star.
