I think people's perspective of Panzo is poisoned by a recency bias, particularly after what happened in the play-off final. He wasn't actually a bad player, he just fell out of form and was probably lacking in confidence after being displaced by Callum Doyle (who was class) in the latter half of the season. Realistically, as a left-footed CB around the age of 22-23, he currently fits our model of recruitment, and I think people have written him off far too soon. There's no doubt a decent player there imo. Definitely wouldn't mind having him back, especially for some much needed squad depth in the defensive department.
Alternatively, I also wouldn't mind taking a punt at Humphreys who would seem to offer some potentially similar qualities minus the trauma attached to Panzo due to that play-off incident
