A strong skater and puck mover with a powerful shot, Johnson has the skill set to play the role of power-play quarterback or triggerman. As one of the best all-around defensemen in the NHL, he regularly logs more than 23 minutes of ice time per game.
The Carolina Hurricanes selected the Indianapolis native with the No. 3 pick in the 2005 NHL Draft, but Johnson never played for the team. After spending the 2005-06 season at the University of Michigan, where he set school freshman records for points (32) and penalty minutes (149), Johnson was traded to the Los Angeles Kings on Sept. 29, 2006.
