Shaun Wane.
My reasoning is that i don't think we should go with another rookie or someone with a poor record.
Wane has had a successful career in England a couple of titles and multiple GF appearances.
he would have some idea what it takes to coach at a prestigious club (although Wigan obviously still wouldn't have the pressures that coaching the Brisbane Broncos comes with)
I realize that the ESL isn't as strong as the NRL ... but IMO he is still a better option that the other possible options.
I would also try to get Kevvie in as an assistant, because IMO, he is a fantastic assistant coach (although i don't rate him as a head coach). if he truly want to help the club out of this mess, then his ego won't stop him taking an assistants role. Kevvie would help restore club culture and pride in the jersey (he doesn't need to be head coach for this). it would hopefully sate the old boys and stop them trying to undermine the coach and the club every chance they get. we could allow Walters to keep his QLD gig.
just my 2 cents
