You two appear to be arguing two different things. You're talking more about Doughty's shift to shift contributions, and you're right that his play was very good and very valuable. He seems to be talking more about Doughty's discipline, and I agree with him, too, that Doughty's shortage of that was a negative. He got frustrated in Game 1 and went for a big hit that led to him missing a game. When he returned in Game 3, his clapping act with seconds left in the 2nd period might've motivated the Knights during the intermission and contributed to them playing much, much better in the 3rd period. Add his quotes in between games and the series was largely about him, not the team, which was probably somewhat distracting for his teammates who desperately needed to focus on on-ice issues. Basically, his individual performance was terrific, as usual, but might've negated much of that benefit to his team by costing it in other ways.
He quite literally said "he didn't play well." Re: the discipline that's debatable and a lot of conjecture/supposition, but I'd concede if it were just that.
