Flanagan took the team to within minutes of a gf last year, so there's that.. Which is nice.
He did (if by minutes you mean about 85 minutes).
And he has his good points.
Keeping players happy and attracting players seem to have been two of his strong points.
But there is no doubt the club has had some of its worst times ever with him at the helm (or with Stuart, who he was assistant to and seems to have inherited a lot of his flaws). And IF the club folds (and I hope it doesn't, but it is now a greater reality due to Flanagan than probably any time since I've supported the Sharks) he will rightly be seen as one of the all time villains in the history of the club.
I feel sorry for him too, since I doubt the culture that saw him very early on in his career, get blamed for lack of oversight was entirely of his making. I can imagine that Stuart, and the board, and probably my sacred cow (according to Feej...) Gallen (and all players, they are all a bit responsible for club culture, both good and bad) had their parts to play in that (plus our seemingly precarious financial situation at the time probably didn't help). I doubt Flanagan could just have completely overturned whatever systems and culture were already in place in the first few months of his career as top coach.
But the coach has to shoulder the blame, and his lack of authority and/or sense contributed, and either (or both) of these traits are not necessarily a good thing for our future, especially with the board we have, the media scrutiny we are under, and the sacred cow as captain.
