Has Faulk regressed? Defensively, yes. I see a difference between 2013 Faulk and 2018 Faulk. To put it into perspective, earlier in his career, Faulk made the U.S. Olympic team with 30 point caliber production. As his offense started to develop, week to week consistency in the defensive zone became an issue. As time has further progressed, particularly after the Malone injury, it’s become a game to game, or even shift to shift type of deal. It's been a weird development curve.
I do wonder that if put in a system that limits his ability to aggressively gap up in the neutral zone, if his defense would stabilize. Faulk gets caught flat footed in the NZ more than any defenseman I can think of.
Offensively, I attribute the decline in numbers mostly to puck luck. His assists totals aren't going to be anything special on a team like Carolina; he's a goal scorer not a playmaker. In terms of goalscoring, Faulk is shooting at less than ~50% of his post-breakout percentage this season. I expect that to come back to the mean next season. He has 15-20 goal upside no problem. For that, I’m more hesitant than most to move on from him. We could easily be sitting here next year once again talking about how silly the idea of Faulk for RNH is, from a Carolina perspective.
