I think he had more value last year before the draft.
I think he has more value NOW because the 'deadline' deals last year with such big names like Kidd and Shaq didn't seem to work out very well (whether (i can't spell that word right now for the life of me) they should have done better or not is up for debate, but the perception is that those mid season trades were failures), I think miller would be seen only for the expiring deal at the deadline. However, if a team is thinking they are a point guard away from making a serious run this season miller has value as a player AND an expiring deal.
Miller isn't jason kidd - reputation matters - past performance matters, who cares how much they stink now - so people might thinkk - couldnt' get it done with kidd mid season how can miller help?
Mid season trades iin most sports hardly ever win a title - and unless you have two real desparate teams, you aren't going to get a great deal for him. Offseason, more teams might be interested....hell the hawks might be interested as a one year stop gap to build upon last year, you never know.
