I appreciate your insight into AFCB having worked there,and observations on EH. However (excuse the pun) I'm not convinced that this AFCB-Saints thing will be so ingrained that he would not want to come to us. We all know this 'rivalry' is a 'lets pretend' one, and deep down so does any Cherries fan with half a brain.
His time at Skates is,with respect to him as a player, is the highest level he played at so will be a time he remembers fondly.
Many a scouser has played for and been involved with the other team in their city,so I don't see this 'tribal' thing preventing EH from coming to us.
He might not be the first choice I would make,there are others ahead of him in terms of experience and potential, but he would not be last resort in my book.I'd certainly rather have the ambition/promise of a young manager such as EH, than a recycled rent a job such as Brown or Hart.
