At the time of signing, there was every reason to believe Doughty would be worth it, as he was coming off a Norris trophy win. He was driving play at an elite rate against tough competition and under new coaching put up a career-high in points. He was a bonafide top-five defenseman and deserved to be paid like one. Based on my research on
term, Doughty was a safe bet to age gracefully based on his standing as an elite defenseman. It’s a deal a majority of people would’ve signed. Maybe a little rich, maybe a little long – but probably worth it in the end.
No one expected the Doughty that showed up in 2018-19. That’s bad luck. He was just average defensively and a complete shell of himself offensively in terms of play-driving. For the first time in his career, Doughty carried a negative expected goal rate and had one of the worst relative rates of his career. By actual goals, it was the worst of his career and he dropped back down to a pedestrian 45 points. By GSVA he was worth just 0.4 wins last season compared to 3.0 and 2.4 the two seasons prior. WAR didn’t like him much either, putting him just below replacement level. You can argue that Doughty struggled because his team did, but part of the team’s struggles are simply on Doughty not playing like the elite defenseman he should be.
