The 29-year-old, who had 45 points (eight goals, 37 assists) in 82 games last season and was minus-34, the worst rating of his 11-season NHL career, criticized his own performance.
"I can't put a measure on how personally motivated I am for this season," Doughty said. "Last season was a disappointment and a big embarrassment. I'm expected to be one of the best guys on my team and a leader. I'm really looking forward to bringing us back to where we need to be. My determination is going to be at (the) maximum."
The Kings have a new coach, Todd McLellan, who replaced Willie Desjardins on April 16. Doughty, who is heading to Los Angeles next week with training camp opening Sept. 12, said he has only spoken briefly with McLellan by phone about what the coach expects of his leaders and the tone he expects them to set in camp. But Doughty said he is very familiar with McLellan, having faced the Sharks frequently when the Kings' Pacific Division rivals were coached by him from 2008-15. McLellan also coached another Pacific team, the Edmonton Oilers, from 2015-18.
The Sharks qualified for the playoffs in each of the first six of McLellan's seven seasons and played the Kings in the playoffs three times in a span of four seasons from 2010-11 through 2013-14.
"He had some really good teams there. We had some great battles with those teams," Doughty said. "They played hard and played that old-school style -- hard, nitty gritty, finish checks and going hard to the net. It wasn't all that pretty stuff, not a team that relies on its power play or anything like that, but just a good 5-on-5 team that always buckled down and played hard for each other."
