He was named to the second all-star team and was named a finalist for the Norris Trophy as the league's top defenceman. His coach, Terry Murray, praised Doughty for his improvement during the season. Doughty helped lead the Kings into the playoffs for the first time since 2002, though they lost their first round series to the Vancouver Canucks. He played all six games of the series despite suffering a wrist injury in the first game that forced him to decline an invitation to play for Canada at the 2010 Men's World Ice Hockey Championships.
