I didn't say that last year, nor did the people who I think of as knowledgeable posters.
Chabot had struggles last year, and the cracks were beginning to show, but that just means he isn't a 27 minute a night DMan. He does certain things extremely well and has shown in the past he can be a reliable, albeit beatable, defender.
Chabot can easily be a 22.5-24.5min D who is elite on the breakout, in transition/in the neutral zone, good goal scoring and o-zone play, good option on PP1 or PP2, 40-50pt a year DMan who can skate with just about anyone. Maybe he "only" ends up a Jay Bouwmeester. But Chabot is extremely skilled, athletic, and we have seen it when he's not exhausted - he's a smart player.
I think you just have a short memory, and maybe short patience.
