Jordan has some big deficiencies in his game (maturity, and free-throw shooting most prominent). I am not sure he would be in my top 3 (realistic pickups) even if he was a free agent this summer. His contract isn't max yet I think he is slightly overpaid (all Centers are though). Check out him against Leonard this year: http://bkref.com/tiny/Rylmf Not a huge difference (I am sure his D is light years better though) compared to price. Now if it was only Freeland and a pick in cost cutting move sure. Doubt they do that though.
Maynor's been pretty much 'meh' for a while now. No need to extend him a Q.O., is there? There should be some decent options available for the MLE that could actually improve the team.
I think DJ Augustin could be a sleeper value as a back-up PG. His advanced stats are actually OK given his USG, and he is a pass-first guy who can facilitate a bench with a few scorers.
I think Jack might actually get a shot at starting somewhere next year. He's only 29, and for as much as he was hated as a Blazer, has been a fairly average PG for most of his career, and now has an outside shot.
Remember the confusion over 2011 #57 Targuy Ngombo? Minnesota had us pick him for them, but it turned out they didn't get Dallas' pick after all. Stern later had Minny pay us and Dallas each a late #2 in compensation.
