Your rose-tinted glasses are working well.
Shittu has had one great performance for Bolton - at The Emirates a year ago. Most of his other full or part appearances has been littered with mistakes, one of which has normally resulted in a goal. Don't get me wrong, I agree he will do an ok job but alongside any other central defender than Cahill and I'm worried.
As for Nicky Hunt, I can't recall a single appearance for Bolton at centre back. He had a few for the U21s, I'll give you that.
