Well, this league is kinda soft. Playoffs rules change.
Regular season Chiarot, I'll give you the he's not worth the hype, but the way he plays is prime playoffs.
Forwards for a hit on him and they bounce off, then he demolishes them, or makes them pay for going to the net.
His offense that he shows/has showed I wouldn't count on it once the playoffs start. Anything he produces is "found money"
His advanced numbers look bad, or likely do. However, they almost certainly don't and likely can't take into account how much a team has sucked at points in their season.
In short, he's a big, mean, punishing dman that blocks shots, throws hits, clears the net and can fight. His puck moving abilities are decent. Boomer shot, but wouldn't count on offense from him. If you are counting on him to provide offense, then your team isn't ready and you shouldn't trade for him.
