I dont think that many of us underrates him.
He gets a lot of criticism due to his role, not how he plays. Put DD on the middle 6 and Im pretty sure he won't get criticize anymore.
If he's good enough and I think he is, he can easily produce like any middle 6 player in the league but hard to blame those who are not happy to see DD playing the most important role as a forward which is the #1 offensive center.
The problem is that we don't have spot in the middle 6 for him, especially at center.
Bold: I'd bet my life savings he would.
I see him as a 2nd line C personally.
50% or so faceoff guy

Add the fact I think his D game is underrated. I don't think he's as good as Plekanec or Eller but I don't think his Parros on the ice either. He backchecks hard and does fairly cell in the neutral zone. The area of weakness is despite his work ethic and drive his board battles are far legendary. He doesn't have the size to be dominant there and he's not a shot blocker type either. He has no physical game either. So overall his defensive game relative to a Plekanec, Backes, etc... is weak but it's NHL caliber IMO. I don't think he's a liability that some claim. I think he's just a guy who doesn't excel at that. Slightly below average IMO, not terrible though.
Still, I genuinely think the fans on this board are really over doing it with regards to him. He's not a #1C offensively or defensively, he isn't. Yet many questioned his ability to be an NHL player, that's just too much. He's got skills that a team can use and despite what people think I feel guys like Bourque benefit off playing with guys like DD. Eller and Plekanec aren't pass first centers so guys like Bourque don't do as well as we'd like with them.
I've openly said I'd try the following combos with DD in it:
Pacioretty-Plekanec-Parenteau
Galchenyuk-DD-Gallagher/Sekac/Whoever
Bourque-Eller-Gallagher/Sekac/Whoever
OR
Galchenyuk-DD-Bourque
OR
Pacioretty-DD-Gallagher/Parenteau(the current one)
and even him as a winger:
Pacioretty-Eller-DD
I think there's plenty of opportunity here. I don't even feel he's a great PP player, I think he's decent-good but nothing special so his PP time doesn't mean **** to me. I think he can be good at ES though. I see why he plays the ES minutes he does though, he's not a defense first center so it wouldn't really help the team. Still, there's compromise and ways to make an ideal fit for everyone with more balance. I don't feel that DD stops us from doing anything really. I think he's a good enough player that he can adapt. My issue comes primarly from those who think he sucks no matter what and those who feel we'd do X times better just by getting rid of him. That doesn't make sense to me. Replace him with a winger? Sure. Trade him for nothing or a pick? How are we better? If this is overrating him then people need their head checked. This isn't an extreme opinion.
End of the day, I absolutely disagree with you saying not many of us underrate him. I think the majority of those who discuss DD here do. Some to extremes and others less. The number of posters who overrate him? You can count it on one hand and have fingers to spare.
