According to Chicago Tribune Chicago is working on a trade to get Mgrady's expiring contract. They don't want Hinrch or Sslmons, so they are looking for a third.

I'm not familiar enough with the trade rules and cap, but the ESPN Trade Machine approved:
Bos KHinrch
Chicago McGrady Houston and Scal from Bos
Houston gets MIller, TThomas Chicago and House and TAllen Boston
