What about Tyson Chandler and Beno for IT, Terry, and Landry. It works on the Trade Machine. If we can't deal Terry, DWill has a similar contract. If they don't want Landry, JT could fit the bill (though JT makes sense as a perfect third big behind Cousins and Chandler)
Chandler is a huge contract, but he has only two years, so you shed two years off of the Landry commitment at the time you need the money to resign Gay. Chandler seems like a great fit next to Cousins and Gay. Sure, you are short in the backcourt, but Beno can serve out the year with Ben, Jimmer, and Ray, and you can address that in the draft or free agency.
