unless there is a clearly better option ... then yes. Kevin Walters in NOT a clearly better option. His head coaching record in an easier comp for Catalans is poor (actually worse than Seibs current record). I think time may have passed Kevvie, because the fact that at 52, he still hasn't been offered a head coaching role, and that is telling IMO.
i'd actually like to see if he can get us out of this slump. it could be the making of him as a coach.
you have a look at someone like Brad Arthur, who really struggled for a year or two, but once he was able to make some changes to the roster, is now going really well.
even the great Wayne Bennett had mass calls for his sacking in 91, but the club stuck by him and the rest as they say is history.
