In 2013? I can't even remember who was available. I think sometimes these decisions can be over-thought. We've seen the best managers go somewhere and been awful, and those that you'd never think in a million years would work, end up signing for a team and it's a match made in heaven. What we should have done post-Ferguson was be more decisive. Moyes getting to, what was it, April(?), was ridiculous. It was the mindset of 'Ferguson was here for 400 years therefore all it takes is for someone to manage us for a really long time and they'll be successful'. I found that disrespectful towards Ferguson's talents as if that's all it was. It was also dumb from our perspective.
Moyes wasn't a bad appointment. No manager is. Well, few. Not at the time. The bad decision comes when you deny reality about how they're doing.
"Okay so the house is on fire, the dog has been shot and the kids have been murdered in the back garden, but we're only in February, if we act now someone might think of us of being trigger happy, and gosh we wouldn't want anyone to be gossiping like that about us!" attitude. We could have moved on from Moyes midway through that season and salvaged it. Replace him with whoever. Doesn't work? Be decisive, until we find someone who does.
