I don't think the other poster called Helm/Cogliano specifically as these kinds of "dinosaur" type defensive players, but I'm not sure what his opinions really are.But isn't that contrary to what the other person was saying? Guys like Helm and Cogliano are the type of "defensive forwards" that dinosaur GMs love even if they're not actually good at generating offense/puck possession outside of their own zone. Their lack of any sort of offensive driving contributions seems to run counter to what that person is saying since those are the type of "defense only" players that coaches and GMs always seem to love.
And Manson is further proof based on his last couple of seasons of analytics. At one time he was an analytics darling, but he hasn't been that the last little bit. Instead, he's more of a "eye test monster" who GMs love due to his physicality and perceived defensive ability, despite the analytics saying otherwise. Yet he was a prime target for Sakic.
I'm not saying none of Sakic's moves were analytics driven, I'm just saying that the guys I mentioned above seem to fall more into that "old school dinosaur GM" approach to why they were acquired rather than because they had stellar analytics.
I think analytics are good at highlighting which players are actually good defensively. I think in the past, there were many players that had reputations as strong defensive players, that weren't really true. Like, a guy like Manson has historically had pretty good defensive metrics. He also looks like a good eye test guy. A guy like Ristolainen is someone people held in high regard for a while because he looks like a good defender, until his reputation caught up with the analytics - which always viewed him as poor defensively. It's the latter types that are the misses/dinosaurs, IMO.
Guys like Helm/Cogliano have always had good defensive metrics, that fit their eye test reputation. It's true their overall impact isn't great because they don't drive much/any offense, but their role is really to just go out there and have nothing happen for either team. And they accomplish that. At forward, a more "Ristolainen" type example might be someone like Scott Laughton, who seems regarded as a strong two-way/defensive forward, but some of his defensive metrics would disagree.
