Parramatta have won 83.3% (5 from 6) of games he has refereed, while Penrith have only won 33.3% (1 from 3), but it's only his first season so the chances of him getting the GF are less than zero.
Out of the more experienced refs, probably Chris Sutton, but he rarely referees Parramatta games, only 18 in 11 seasons.
As for the biggest a-hole, it has to be Grant Atkins, a biased campaigner who he hates Parramatta and loves Penrith. If he was on fire I'd pour kerosene and lighter fluid on him while I toast marshmellows and sip champagne.
I don't believe that any ref 'hates' any team in the comp. Or in SL, for that matter.
Perceiving that the game is 'bent; is schoolboy conspiracy stuff. Anyone who thinks that is a bit of an idiot in my book. As I've remarked before, if you really believe the game is bent, why the hell are still bothering watching?
