He has been there since 2014 (so six seasons) and two of those were playoffs (one preliminary final, one grand Final so far)
If he does pull it off he's been able to get a Premiereship each decade, which is impressive in itself because there were different challenges to being a coach when he was first coaching to the present.
His record this decade though before this season kicked off was ordinary, one wooden spoon, one 15th/16 finish and two 10th place finishes with one finals appearance to show for it.
He royally screwed it up at Parramatta and that's probably a black mark on his name. You could almost say his record since his last Grand Final has been rather ordinary with 2 and now three finals appearances since 2004 which is not great.
Although both the Eels and the Sharks were a mess going back to Kearney and Chris Anderson at the Sharks.
A premiereship will buy him some time but in a place like Canberra where expectations aren't as high as Sydney teams he could probably survive doing what he has been doing, with every second year and maybe third being in finals contention. ALthough the Raiders are probably good enough to be a mainstay in the 8 for the time being.
