Mr. Congeniality, decked out in a fine suit, a large grin, a great attitude and, later, a green cap with a big note logo on it, walked into the spotlight at the Jazz's practice facility on Thursday to introduce himself to Salt Lake City. As first acquaintances go, this one wasn't just top-drawer. It was spectacularly sweet and polite. Before he entered the main room for his introduction to the media, 6-foot-9, 245-pound Marvin Williams extended his hand to a complete stranger in the hallway and humbly said: "Hi, I'm Marvin." He went on to do a radio interview during which he revealed his all-time favorite movie was "Coming to America," and his favorite TV show was "Fresh Prince of Bel-Air." Before any questions were asked in the group, Williams took the opportunity to … what's this, express gratitude? No lie. "I'd like to thank everyone for coming," he said, adding what a privilege it was for him to have the chance now to play for the Utah Jazz. He also said he was thrilled to play here.
