Football: SFA whistler rules forcing McCurry out Excerpts from the DailyRecord: TOP whistler Mike McCurry last night admitted he is on the verge of quitting the game because he's grown disillusioned with robotic referees. ...The referee said: "At the moment I'm undecided over anything and everything to do with being a referee. Mid-season is not the best time to come to a hard and fast decision about my future but I will know my own mind better in May when the season ends." ...He said: "I've survived all of the so called chaos games I was ever given to handle and I thrived on doing the' Old Firm derby. "I know I've been mentally tough enough to sustain a refereeing career at the highest level. What I don't know is whether I want to go on doing it under the present circumstances. The fans want to see greater consistency and I can't fully agree with the application of certain laws. There are more and more cards being handed out on a technicality today. ..."The referee's voice has got to be heard on what's going on in the game. ... http://www.dailyrecord.co.uk/sport/sport/tm_objectid=16548403&method=full&siteid=66633&headline=i-d-rather-ouit-than-bean0ther-roboref--name_page.html
The only thing I can find is that he's mad at the way SFA is instructing it's referees, none of the articles I found go into any detail though.
