There's a very good chance a trade happens. The Cs understand that their cap situation is compromised for the coming two years, so their best chance to add a complimentary talent for this year and next is via the nice mix-and-match of expirings we currently have.
I'm not talking about Ray -- his deal is too big for the amount they'd likely have to commit to next year and they want to keep him. Same applies for Pierce next year. The Cs could trade for a player or players making anything from $1 to $12,000,000 this year without trading Ray or Daniels. And remember, if the Cs want to sign Daniels again this summer, they have to use the MLE to do so.
Look for them to continue to target teams going nowhere. Washington, GSW, Phili, NJ, etc...
