Stockton holds the Spurs' opponent record for most assists in a game, with 28 at Salt Lake City on Jan. 15, 1991. Jazz coach Tyrone Corbin said Stockton was one of the "toughest competitors I played against and with as a teammate." Jazz CEO Greg Miller tweeted that he had a `nice visit with Stockton on this 12-12-12" and thanked him for all he's done. ...
