Okay, one last post.
This is a simplified, hyperbolic sentiment, but generally accurate. I would add that being stubborn about return value on Al (or Sap, or whatever vet) isn't going to be the difference between getting a little or getting a haul, but it could easily be the difference between getting a little something and opportunities for players that haven't reached their ceilings and absolutely squat.
Al is not going to get you much, but he's better than some other expiring players and some teams might throw in SOMETHING that the Jazz could potentially use (take a pick of or mix and match late 1sts, 2nds, or rookie-scale player that isn't getting chances [because they're likely buried under veterans where THEY are at as this would likely be a playoff team that is less concerned with development or whatever). The opportunities for Favors and Kanter - notwithstanding that it would force the offense to open up - is worth it alone.
