Your personal and persisting obsession about Therrien. NHL Teams are filled with bullies and dinosaurs. Get over it. When you post angry posts like this you sounds like a 12 y teenager. 31 teams don't win the Cup every year. There are teams who haven't won anything and I don't think they have angry fans like you, except surely Toronto.
Now I have to be in an unconfort position : defend Therrien, omg, I hate that. He was a nhl coach, you and me : not. He made Chuck having his best carreer year, right? He lead the Habs with more pts in a season than a lot of coaches never did in 25 years, right? There is little credit on his side. He was the coach when Crosby started to be a star and he went to the SCF. Now, I don't like him but he's not the monster you depict. There are shades of grey.
I don't think MT was a good coach, but he's not the reason why Galchenyuk isn't producing Kane/McDavid/Crosby. Can't help but look at Morgan Rielly who had terrible d partners for years, and had two incredibly toxic coaches in Carlyle and Babcock (who's done far more abusive things than what we've read/seen from MT) yet he didn't fall apart like Galchenyuk.
I do think the development sucks and is largely to blame, I've made that very clear. For instance, the fact that McCarron and Poehling are doing well as bottom 6 centers elsewhere supports this. These are genuine examples of us poorly developing a player. That being said, are those two players key players? That to me shows that Timmins can't draft helpful talent consistently like other teams, and the few low-upside players that do make it weren't properly developed.
You look at a guy like Suzuki who was playing right wing with Weal and Thompson on the 4th line and we still developed him excellently. The difference is that we acquired Suzuki since Timmins couldn't draft a forward like him. Danault is another example of a player we developed but we also didn't draft him.
While both are to blame, it's definitely drafting that was the bigger issue.
