I thought the same thing.
If the Spurs ARE fielding offers for Parker, they'd better get back their pick and a player in exchange for him. If Parker is indeed the trade bait and if Sacto is the trading partner, they'd better get back both their pick and a player like Omri Casspi. Imagine it. In such a scenario, the Spurs come away with Casspi and the #7 pick in the draft.
I would give anything to know which player they would be hot after, if they did this deal. I don't necessarily condone getting rid of Parker, I'd rather they trade Hill instead, but Parker obviously would net the best trade value.
Either way, a trade of this type would help stop some of the bleeding and plug some of the lineup cracks that have been exposed.
