Twelve posts later, you finally arrive at a (somewhat) substantive response.
Slow clap.
I think on draft day, Zboril was the consensus better D. Today, I'm not sure.
I think points don't mean "everything", but as Dr. Quincy has aptly argued, they're an important indicator at this stage, especially for high upside D prospects.
Last season, Zboril had to adjust to being tasked with a more defensive deployment than his previous season, and it obviously reflected in his weaker offensive output. You could argue that last year, Zboril had a heavier D role, thus explaining his weaker offensive production. But Chabot was also deployed in all situations. And played on the second penalty kill unit for the Sea Dogs (he had a short handed goal, for example, while Zboril did not).
To me, the difference became apparent in watching both at the World Juniors. Chabot had a breakout performance, with 3 pts in 5 games, and played as Canada's top pairing (beside Joe Hicketts). He was deployed in all situations and played a big role in carrying Canada as far as they went. Zboril simply wasn't nearly as impressive in the tournament, and in the games I watched, sometimes seemed unfocused/disinterested, and would disappear for large stretches.
This year, both Zboril and Chabot are playing heavy minutes and are also getting power play time (5 of Zboril's 6 goals came on PP, while all 3 of Chabot's); in these top D roles, Chabot is simply out-producing Zboril, which is important if we want to project which might be a #1 or 2 D long term in the NHL, which is was my original point.
And yes, while Chabot only played a single game, he was still assessed good enough to retain for the entire pre-season and then start the season as a 7th Defenceman through a long Senator road trip at the beginning of the season. You could argue that had Ottawa been stronger defensively, he may have had more of a chance. Zboril, by contrast, was sent down after only 4 pre-season games. That's unlike Debrusk who received an extended look in pre-season.
To me, this and Chabot's better stats are just a reflection of the stronger performances I saw at World Juniors.
I would have mentioned all this in my original post had I known I'd have to defend myself against multiple laughable caricatures of my modest point about comparing point production at the Q level for high end D prospects who literally play on the same team.
I could have also simply responded with a similar dismissive response "because points are irrelevant, especially to high end D prospects". But I didn't because I'm a nice guy who takes your posts seriously.
