Have you watched Klefbom , the kids a stud. Hall pushed hard?
So every prospect that makes it, its because they're a cant miss prospect and they hit the ground running and are expected to be great but the ones who don't its because the Oil organization handled them wrong,not buying it.
Hall had some great years in Edmaonton and Klefbom is one of the best defenseman in the NHL today. As far as RNH he is what he is, that has nothing to do with the way the oil handled him.
Their problem Lies with Chia , he's litterally destroyed that team with some bad decision making or they would be mopping up the League.
Each team is going to have a Bust and missed picks and from what I've seen of Puljujarvi he is just that, its nothing to do with the way the oil have handled him. He is what he is and he isn't going to fetch much of a return and mostly diffidently not a Danton Heinen and a first round pick.
