Agreed, though perhaps the hindsight argument could be applied.
I was surprised that Aberdeen went for Goodwin, to be honest. After taking a punt on Glass, I thought they would go down the more proven manager route. If for no other reason than to regain a bit of credibility.
Jim hadn't achieved anything of significant note, unlike Jack Ross, who at least was coming off the back of a fantastic season and league championship.
I might be being unduly cynical, but I think both Ross and Goodwin are/were articulate, assured, and very media friendly. This resulted in them being touted as the next big thing in their respective moments. That seemed to overshadow their actual and potential limitations.
ETA: consider Martindale by way of contrast. A more rough and ready character who, despite his very significant achievements against considerable odds, tends to be less often touted and, by association, courted.
