It's very interesting, this. I agree with pretty much all of that really, but where I think you're being a touch disingenuous is by suggesting Hughton was dealt some crap cards and that this is highlighted by the fact that Potter has discarded them.That "reality" is only your perception.
I hear a lot about CH not making the most of the squad of players he had, but I don't see it. For me, we were a bottom 5 squad for both of those seasons, and he finished near the top of the bottom 5. Many managers would have sunk without a trace with that squad. Take a look back at the horror on here that we didn't sign a striker after promotion, and were going in with Murray as our main man still. The view was generally "if we can stay in touch of survival and sign a striker in January, we may just be ok". We were much more than ok, and he did that without a decent striker being signed in the January, or the following summer, or January. Tell us that in August 2019, and we'd have never believed we were staying up.
Was it pretty? No. Was he out for survival? Yes. But I don't agree that he was given a whole host of great players that he didn't make the best of. Potter has already binned off some off the rubbish CH was having to make a silk purse out of. I don't think time will show that the sum of the parts CH was given were better than merely survival by whatever means necessary.
That is all true but you neglect to reach the obvious conclusion: Hughton had a hand in the recruitment of those players, and also that his biggest mistake was his lack of trust in the kids, many of whom are clearly quite good. Potter saw this and has given them all a chance. You can't gloss over the fact that Potter has binned off certain moderately expensive signings without also admiring the fact that he has replaced them with academy signings AND got us playing in a way that is frankly a joy to watch.
Hughton was a fabulous manager for us - one of the, maybe THE best we've ever had. But Potter is destined for the very top IMO. Whether or not he ends up being spoken in the same breath here as Mullery #1, Adams #1 or Sir Chris will entirely depend on how long we can keep hold of him. Man Utd would kill for someone of his competency for a start.
