There is no report to the effect that the Spurs are interested in Garnett.
A blogger in San Antonio wrote a column saying that Garnett is a free agent and it would be awesome if the Spurs put Garnett and Duncan together. Not only is there no source, the blog doesn't actually even insinuate that the Spurs are interested.
It is a non-story. ESPN rumors picked it up, WEEI passed it along as a story, but it is no more a story than any of our posts on this message board.
