I'm actually struggling to think of a player that fans have more gleefully wanted to fail at any point in the 25 years I've watched us.
He isn't a particularly good keeper, even in his better spells it's been clear that we could improve on him a lot, but the overreaction to a lot of what he's done on the pitch has probably contributed to his confidence with a knock-on effect to his development.
Yes, despite this, he should recognise that this is a high pressure position and whether he's up to it characterwise (Wilder pretty much alluded to this in an interview last month).
I'm delighted that we at last seem to have found someone in Moore that seems to be an improvement on Long's agility while being vocal and confident. We've needed someone like him since Kenny left. But that doesn't excuse the attitude of plenty of self-defeating fans that have jumped on him at the slightest mistake at a game (or, more ridiculously, had a go at him after doing something decent – as happened away at Walsall last year).
He will probably fashion a career at League 1/2 or in Scotland, and I suspect wherever he goes next he will be a lot happier. We've had far shitter players that have taken a hell of a lot less grief than Long has – and for his part, while not being that good last season he came back into the team at a time confidence in Howard was plummeting week-by-week.
