Doughty is known around the league as one of the best trash talkers and irritants (by said trash talking), more proof.
Kind of funny I posted that link the other day and he just mocks Marroon big time and then this, but Burrows and the Kings have a history starting when Richards just destroyed him in Game 1 of the WCQFs in 2012 and Lucic from the year before and the whole hand biting incident in the Boston/Vancouver SCFs.
I think the Kings just like messing with him because he's such an easy target.
