My guess: Spurs re-sign Diaw, sign LJC and use the MLE to sign three prospects to long-term, Blair-like deals. They may also use their pick on a domestic player, but I think they stash him unless he's a steal.
Bertans, Denmon and Richards are my three, but they may bring in Thomas for Richards, as his ship may have sailed. See Mills moving on along with Baynes.
That sets up the team in great position for 2015, while giving a lot of young players time in Austin.
