Sacking is not always the best option though. Simmons has been having a tough time, but he's proven more as a coach than Cunningham, whats to say Cunningham won't do worse?
When we sacked Macca and St Hilaire took over, we saw no improvement.
Think Saints have jumped the gun a bit (admittedly I don't see them on a week to week basis) as Simmons did ok last season. Roby is integral to that Saints side. Think Saints rely on him more than any other club rely on a player in the league (think only Sinfield comes close) so to be without him plus LMS, Soliola etc you are going to struggle.
