Its a debate that will rumble on until SS leaves the club for whatever reason he decides to leave. There will always be fans at any club who want a new owner, be that results are bad, manager choices are not what they want, the way a chairman treats fans, or in the case of a couple of clubs, the whole human rights reasons.
From a personal point of view (and most likely the view of an awful lot of fans) id thank SS for taking over the club, when most of us hadn't set foot in BR for 5/6 years. I've met people since our return that I would call very close friends, spent many weekends with them, drinking at away games, even seeing them when there is no football on. To be that's what supporting a football club is about. Yes we all want to win every week, we all want to watch entertaining football, and we all want promotion. If you think SS doesn't want that too, then give your head a wobble.
He has made quite a few mistakes, all in my opinion on manager appointments. But his reasoning for giving those people jobs is sound. Grayson, in his interview, he said he had achieved 4 promotions from this league, and gave him the job what, 3 weeks after coming in as owner. I get his reasons for this, but he also acted quickly when things turned sour inside the ground.
Appleton the same, he may well have waited too long to sack him, but, as an owner, and someone who made that decision, you want it to work, you want it to be a success, and sometimes in football owners are too quick to make changes. but he wasnt afraid to sack him, again when things got sour in the fround. We will never know if sacking him and giving Dobbie (for example) the job there and then would have worked, and there will have been reasons why he didn't go down that route. As fans we are all entitled to our opinion, but if we or he acted on every opinion each of our fans have on a Saturday or Tuesday, then god only knows where we would be now.
Critch will always divide opinion. His first full season, where we gained promotion, he could easily have sacked him after what, 10 games(?) when we were in the bottom three and looking pathetic, but he didn't, stuck with him, and look where we ended up. We are currently 9th in the league, with 11 games left, and yes, i agree its looking unlikely, but stranger things have happened with this club, and as an owner, who has put faith in a manager, who he is aware of what he does day in day out (and not just a 90 minute football match once or twice a week) and im ok with that.
He is a fan like the rest of us, and of course he will be hurting (like the rest of us) when we lose games in the manner we have done throughout the season. However, we have a club, we have a chance to meet friends, and discuss these things in a pub on a Saturday, and can enter the ground knowing its a million miles away from where it was 5+ years ago. For a man that has made his millions from tough decisions, I'm confident that the club will be just fine, and if next season it doesn't work, and Critch leaves, we will be just fine.
