All the Spurs can offer is the veteran's minimum. Because they were under the salary cap they don't get a midlevel exemption (same is true about every team under the cap).
Luis Scola has too large of a buy out with his Euro team.
Horry, based on rumors, is entertaining an offer from Miami to rejoin Shaq.
Spurs are still in touch with Malone but again will let him see if anything better than vet minimum is available.
Spurs will bring in some other bodies but at this point need to wait and see who is available for the minimum. Also Pop will continue to shop Malik.
