As a hockey fan, I'm thrilled to see Burke in Calgary. In the NHL for that matter, but especially a hockey hotbed (though the limp Calgary media will be a light lunch for Burke, hopefully the national media still holds a bit of a grudge). Burke is a great villain - in no small part because of how deeply he views himself as a hero - and the NHL needs great villains. Hockey is far more interesting with Brian Burke involved.
As an Oiler fan, I'm a little wary about seeing him in Calgary. Burke is a good GM. He's not as good as he was made out to be when he jumped from Anaheim to Toronto, and he's certainly not as good as he thinks he is, but he's a good GM. He's better than most. He's an amazing trader - look at the players he acquired in Toronto for almost nothing: Phaneuf, Lupul, Gardiner, Franson. Heck, even the Kessel deal isn't god-awful (though made worse by the fact that he could have saved himself a 1st rounder if he just played the RFA offer sheet a bit harder... but no, Brian Burke couldn't do that, could he? Not after the Penner nonsense.
Burke is probably good enough to turn Calgary into... well, the Toronto Maple Leafs. An okay team with some big plusses and significant minuses that may or may not play its way into playoff contention, but probably not Cup contention, each year for the next 5.
Unless he's learned from his mistakes, and can honestly look at his faults as Toronto GM and rectify those while retaining his strengths. If that's the case, watch out for Calgary.
But it's Brian Burke. Does anybody really think he's going to honestly self-assess? Of course not. Burke's the sort of guy who, if someone said he should be Jesus, would say that he was offered the job, but it's too much politics and campaigning, and he'd rather just spend his time feeding the poor and curing the sick without much fanfare. And he'd call 5 press-conferences to announce this.
He's the Donald Trump of the NHL. I am so so so so so happy he's back.
