My recollection is that Higham was replaced by Mark Riddell, who was a totally different type of player. He was bought to bring some control to the play, and was very much a similar style to MMc, not flashy, got the job done, a very good passer of the ball.
The players reckoned he was the toughest in the group, but he was useless in his first season, until Madge got hold of him, made him lose weight and he started to prosper.
Higham was ok at Wigan but Brian Noble didn't fancy him, thought he was a headless chicken. He spent his whole time at Wigan trying to get Terry Newton back. It was Millward's brainwave to get rid.
Higham's done well at Wire. But he only plays half a game at most. Defo better than most though. I'd put Roby, Lunt, Clark, Hodgson, Houghton, MMc, Monas & Henderson ahead of him (not in that order necessarily)
