I don't think Rielly is underrated on CapFriendly. He shows up on everyones top defensemen lists, etc. To be underrated he'd have to be thought of a top 5 defensemen or something.
IMO everyone on list is appreciated by their fan bases and others. I would counter with:
Huberdeau
J.T Miller
Nylander
Gallagher
Dumoulin
Garland
Brock Nelson
Ellar
I agree about Mitch Marner. So many people say he's useless or something, idk. Of course, most people know he's a great player, but some people think he's bad just because of his contract.

Mostly value in mock trades, but also discussion or top 10 lists for players who are never in mock trades (Malkin)
Gotcha. Putting the Leaf players aside because I'm biased, the only player I disagree with is Carlo. That's just based on my interactions with people on this site, though. I've often thought he was more hyped up as a defensive stalwart than warranted. Solid 2nd pair Dman who's strength is his defensive game, but not much more, imo.
