NEW POINT GUARD Mike Conley may not get the Grizzlies to the playoffs, but the rookie will have Memphis fans whistling Sweet Georgia Brown at some point this season. Over the summer Conley, 20, honed his Globetrotter-like ball handling skills with hoops instructor Ed Schilling. A video of a typical dribbling drill can be seen at SI.com/clickthis, under the blog entry Keeping the Ball on a String. It's an impressive display: The ambidextrous Conley is equally adept at yo-yoing the ball with both hands. If he shoots half as well as he dribbles, Memphis has a keeper.
