What do I want to happen? I want the Spurs to use the amnesty provision on Jefferson now. I believe that it's the right move for today and tomorrow. It will allow the Spurs to go after either a young swingman prospect or a veteran stopgap in free agency. I also favor using the amnesty card now because it will erase the cloud that would hang over the team; watching Jefferson press to prove he's worth his contract is not something I look forward to witnessing.
But most importantly, I'm afraid of the alternative. If the front office doesn't use the amnesty on Jefferson, their first move will be to pick up the phone and offer Jefferson to a team with cap space while adding multiple draft picks, DeJuan Blair and/or Gary Neal to sweeten the pot. It's the recipe they've used in the past and is surely their Plan B. The last time the Spurs were desperate to dump a salary it belonged to Jackie Butler and was 1/12th as large as Jefferson's current deal ... but that didn't stop San Antonio from using Luis Scola as the pot-sweetener.
In a perfect world, holding onto the amnesty provision could prove savvy. But personally, I don't think the risk of the unknown is worth ignoring the immediate benefits of a clean break.
