I'm not saying CH didn't do a good job with the players he had, or that he's a bad manager generally.
But it is a myth to say that "he signed" all those players, for Brighton (like eg Brentford), have a very sophisticated stats- and analysis-driven recruitment system which relies on a huge network of individuals' input to make it work:

Within that set-up, the manager (head coach?) will obviously have a say on signings, but by no means the final one, never mind the only one.
And in the wider context, this excerpt is notable:
"The approach is not just restricted to players. There is little doubt analytics and data played a part in putting Graham Potter in Bloom’s sights before Potter had even left little-known Ostersunds for Swansea City."
In other words, regardless of how well BHA thought of Hughton, they must have felt their system had identified a better manager in Potter, with their subsequent progress arguing the point very strongly.
