It is now past the 3 PM Eastern deadline on Thursday and that means that the Cavaliers are 99% likely to stand pat. There's always the slightest of chances that a trade could get through past the deadline if it were filed to the league before three o'clock, but it's unlikely.
Of course, Chris Grant and Co. already made their splash when they traded Jon Leuer for Wayne Ellington, Marreese Speights, and a future first round pick. But now that's what the Cavs are working with. They will play out the rest of the season with the guys that they have.
Truthfully, I didn't really expect the Cavs to do anything and I'm not disappointed that they didn't. *shrug*
