Outlaw has advanced in his career about as far as he's going to. He's a good energy player off the bench, but with Webster, Batum and Cunningham we already have too many SF's and even at PF, he's behind LA and possibly Pendegraph in the near future. We have to pare down and I don't see him as being so indispensable that we have to bring him back.
As to Blake, he's clearly better than Bayless at PG and who ever knows about Mills. He's a safe back up who can play extended minutes. If he was cheap enough and we had no other alternatives, then I could see him back.
