big thing is Chandler is pretty much gone (with us) after this year.
even if we don't get Carmelo (by trade), the pick carries value for us after the season.
conversely, the Spurs are desperately trying to remain relevent, and this is a big year for them to produce. i assume they are contemplating going this route, and if they consumate this deal, thatl be proof.
for us, Chandler in all liklihood won't be making or breaking anything, conversely. sure, he (could) add to some more wins, but really, he won't be making or breaking a playoff run for us. and if Wilson did, it's a sign of imminent rapage if he did make us, vs break us.
a guy like Walker, or Douglas, who could be a more "pure" 2 for us, and a longer term solution than Wilson, would also get room to grow and show what they got. which makes sense, given the hype and trajectory of these two young players last year for us, and their desire to step it up. Douglas playing damn good, Walker having played exciting ball, getting healthy, shedding weight.
finally, the deal gives us the option to trade for Carmelo asap and perform a rape.
i.e. we keep Gallo
e.g. AR + 2011 pick + 2014 pick + Walker
we play hardball in a win-win situation for us, where the juice is worth our squeeze whether we flip the pick for Carmelo or we wait and sit on it.
