More like threatening to take players unless a massive price was paid and then not taking them when teams refused. If you didn't want them you were better off caving and getting any draft picks or assets you could. They made 0 deals. Unacceptable levels of mismanagement there.
Also, there were several players like Taransenko, Henrique, Duchene, etc and several other legitimate NHLers and instead passed on them. Even if they didn't want these players, 2/3 return first round picks in trade within the next few seasons.
They could have had a better team today and tomorrow. Instead like I mentioned, they chose cap space which is fine I guess except they did nothing positive with it.
