Helps that Gill was about when social media was very much in it's infancy but that didn't protect Ferguson from being called out for being a dinosaur and needing to go. Or Ronaldo being a one trick pony that needed to be sold.
Don't forget that Gill was in charge when we replaced Ronaldo with Valencia. When we failed to buy a centre midfielder window after window. We made bad signings and had bad windows under Gill. Do you forget how bad things got in the media around 2004/2005? If I could be bothered to look for it, there's a fairly infamous article from the time which lambasted Ferguson for ruining his legacy at United, that he was done and needed to go.
The hatred didn't come out for Gill though because the narrative hadn't been drip fed that he was the fall guy. I don't even know what Woodward specifically does day to day, what judgement calls he makes and I've never spoken to him to gauge what he does or doesn't know. Whilst we have organisational failings that I feel land at his door, I don't agree that he's pretty much at fault for everything except manager conferences and the team sheet. The structure will be more complex than that.
Never see anyone calling Matt Judge out, I wonder why that is? David Gill also had a finance background but you didn't see people constantly saying he isn't a 'football person'. It also helped that both Ferguson and Gill didn't have anywhere like the competition to contend with that we do now. We dominated domestic football because we had the financial clout and very few could compete with us, rarely more than one team at a time.
I could go on but I really don't see the point.
