Until he broke out people were in fact calling him a bust. He never actually was a bust, but people were calling him one.
People expect players to rip the league up the moment they come in, some players take a while.
Nobody ever criticized Hall (on the main board) like they do Yakupov now. The biggest knock on Hall was that he was injury prone which was a valid concern but I don't think anybody questioned his hockey abilities.
I have to say that Yakupov is overrated by Oiler fans. The 1st page of this thread is evidence of that, at the least the first several posts are.
There's no way that Yakupov holds more value than Eberle, there's just no way. Also, I'm not convinced that his upside is higher than Eberle's. People seem to forget that Eberle had 34 goals and 76 points just 2 seasons ago. If Yak ever has even one season like that, we should consider ourselves lucky.
The main board does have an irrational hate for him though. The oddest comments are the ones that praise Galchenyuk and Huberdeau as core players while Yak is headed towards bust territory.
I understand why people like him. He's a likeable kid, he's fun to watch when he's on and he does seem to get unfair treatment from the media but HFOil definitely seems to hold him in higher regard than most other hockey people do mainly based on draft pedigree.
I think his value lies somewhere between what HFOil thinks and what the main board thinks.
