I would've loved to have him if it were possible. It really wasn't. They could've amnestied Memo but that wouldn't have been terribly wise (there's no guarantee that the Jazz would've gotten Billups [the amnesty bids are sealed], Billups might have caused problems, Jazz would still have to pay Memo and no longer be able to try use him as an asset whatsoever [like they were able to do with that NJ trade right before the start of the season]).
The part of Stein's tweet that mentioned that the Jazz have been shopping Harris since the D-League showcase makes me think that possibly the Jazz have found a potential 3rd string point guard at the showcase, which might mean that Harris wouldn't need to bring back a point guard in return. They could receive any asset (player, pick, exception).
