OK, I think that the problem with this trade may be that the pick that you got from the sixers isn't going to be listed. Your solution about trading the pick on the 1st day of the 2009 season probably isn't a good one.
I hate to say this because it affects our trade, but I don't think this trade can be go through unless you actually have the 6ers pick on your team. The 6ers aren't able to trade the 2009 pick because they don't have a pick in 2008...
This means that the draft pick the 6ers made is screwed up.
This is why "off the table" deals shouldn't be done.
