The Spurs already had made few deals, but I think they need more to compete for the title this year, rather than being swept 4-0...
They got swept because they were riddled with injury on the playoffs. Key players are out because of injury but they still gave a good fight. If it was otherwise, they have a chance in beating gsw. I think there is no major adjustment needed for spurs, a few adjustment on the front court and they are ready to go.
