He was not "instructed" to "not rebuild"
That's utter bullshit only speculated about by fans.
Go back and listen to Holland's end of year press conferences.
Holland didn't rebuild because Holland didn't want to rebuild.
Holland never "wished" for a proper rebuild.
Jimmy Devellano has confirmed Holland told the Ilitch family to rebuild after the loss to Boston in the playoffs and again after the first lost to Tampa. They wanted to keep the playoff streak going, he warned them it would be at great cost to the future and make the bottom harder... So ummm yeah we do know more about that.
Holland isn't a rah rah rebuilding guy though, never was. I don't think he wanted the tear down version, he has an opportunity in Edmonton to do what he excelled at for most of his career. Take really talented stars and get the other pieces to help them win. I think he will be successful there.
To the topic, Buffalo is in a tough spot. I don't see guys really going to the extent of draft guys denying playing there. But the Pegula's have had a nightmare run here, you wonder how they can run the Bills as well as they do while they run the Sabres so terribly. We used to make similar jokes about the Ilitch family with the Tigers and Wings in the 90s. They eventually figured that out, unfortunately without a championship for the better Tigers. For as passionate as the fan-base is in Buffalo, I hope they get a turnaround soon, brutal stretch.
