The odds that Philly finishes with a worse draft pick than Sacramento this year is rather low. It's a nice prize for Philly and all, but if the Kings are able to use it to sign Monta Ellis and/or Rondo, there's just very little way Philly has a chance to pass them this year. Next year, if that's when Philly finally decides it's time to win again, then maybe, although they just agreed with this trade to take on $9 million of dead money, so it's not clear that 2016 is their time either.
While I wanted Stauskas, I'm quite glad the Celtics didn't do this deal. I don't care about this year's salary space much, but I wouldn't at this point take on $9 million for next year.
