It's a great question Mike, here are some random thoughts:

I thought it was a bonkers gamble to sign him as first choice with no alternatives. Any other posistion a failure can be switched out without huge consequence... Jack Clarke for example. I saw his mistakes for Burnley and thought, 'bloody hell, they must really see something in him!'.
He has huge potential, what he does well is very rare, he has some special qualities for sure, he moves unbelievably for a keeper that size. But it's a big if on the mistakes he makes, with some keepers those disappear quickly with time in goal to 'get your eye in' and get up to the speed of a division, others never improve throughout their career.
I would have picked him to play at Wolves, 100%, but that's not to say he doesn't make me uncomfortable. I do think there are certainly things spectators miss though... for example there were 3 or 4 times Wolves players blazed over the bar from excellent positions... he was on them quick and he's flipping big, it makes strikers look for the corners and rush. I wouldn't be at all surprised if they would have stuck 2 of those past Walton because he's not the same presence. I bet very few have even considered that, and instead would focus on the goal he conceded. To be honest, I think it was deflected off Clarke's boot, I'd love to have that confirmed. Muric saves goals without touching the ball, I'm sure of that.
I don't think I'd have signed him, but I don't know what the other options were, I don't know who that someone else would be. Would I be looking at other keepers in January, yup! Is he crazy talented, yup. Do poor teams make their keepers look worse, yup.
I'd like to look back over what he has done, but my gut says if he comes good and the supporters stay behind him, he'll keep us up.
