Williams chose to sign in Sacramento because he prefers the opportunity to play rather than sit on a contender's bench, says J. Michael Falgoust of USA Today (via Twitter). Falgoust adds that Keith Smart's open-court style also appeals to the former lottery pick (Twitter link).
Williams, 24, was drafted by the Nets in 2009 and traded to the Rockets last season. In his three seasons, the former Louisville Cardinal has averaged 7.4 PPG and 3.9 RPG in 111 career games (20.1 MPG).
The Kings already had an open roster spot, and cleared another by buying out J.J. Hickson, so they won't need to make a move to clear room for Williams. SI.com's Sam Amick first tweeted that the Kings would sign the ex-Rocket.
