I disagree on a few things here:
I don't think Liljegren playing good on the sharks should mean Berube blew it. I have a couple of reasons for that:
1) It's the sharks, playing well on a bad team shouldn't be the standard. He couldn't crack our lineup and not many teams probably wanted it
2) His issue is consistency, he has very low low points and it hasn't even been 20 games on the new team, I'd say give it some time before saying we "blew it"
3) Liljegren was a non-option come playoff time, he was soft, timid, and just passed problems on to his teammates with shit passes. He brought no offence and was a beacon to rally behind for the other team after he gets knocked on his ass for the tenth time. He couldn't play tampa, or florida, or boston.
I also don't think OEL is a terrible signing when he is playing more than liljegren, has the same on ice differential as liljegren (+3), has better relative to team stats, more points, and actually pks 1 minute per game vs 1 minute in 15 games. So he is better than Liljegren in every facet of the game, yet he is terrible and liljegren is amazing? I don't think so.
things panning out are credited to treliving though. I think you gloss over stolarz a little too much, he has been trelivings best signing and has been awesome. He has a .924 and even a healthy woll isn't the defacto starter with how good he has been.
Maybe I look at it from a different view point than you, but IDGAF about 5 years from now, we have this matthews contract left. I used to believe you want to try and build with both future and present in mind, and whilst I still do, I'd much rather mortgage the future to try and make deeps runs vs doing the same thing the previous regime did and remain status quo (first round exits). Even if this means our window closes with no cups a bit early, I'll accept that this is what I wanted and won't complain that management tried going for it.
Some stuff I do agree with though is Reaves, Minten and Kampf. Minten especially since I thought he was a long-shot with his awful production in the WHL last season. Thought he could be the david kampf 4C replacement, starting to think maybe there's more to him. Reaves is awful, but he has found a way to be a 0 through his games, so at least he isn't costing us as much as last year. Kampf could've been replaced by dewar or holmberg, but I guess we really liked what we saw. I think you could probably get out of him fairly easy but we probably like him a lot so we will keep him around.
