I think most of us share those nervous sentiments.
When Hudds were in a dip, they looked poor, but otherwise they not only played good rugby, but always seemed to have a plan (they, along with wigan, really upped the ante in terms of the wrestle a couple of years back). He aslo seemed to bring on young players well.
I'm hoping that the extra amount of pressure/expectation on the palyers and coaching staff at Saints (compared to Hudds) will help iron out the problems his sides have had with inconsistencies.
I would also think that, if he can't make things work at Saints, there's no point in even thinking about a job down under.
