pirateoftheah: Thank you for the info, it is quite interesting! As a casual NFL viewer I cannot judge the ref's performance, so it is good to know you also have critics against them. But what is more important - as I see from your replies - it stays on the healthy side and does not turn into blaming only the officials. I really like this behaviour. For example in Europe the fans, media can debate for weeks if a fault was really a fault or it was a goal or not, etc and totally forgot how the teams played. It should follow the NFL's better method.
Frankly, I'm mostly of the opposite opinion. Refereeing in NA seems rather soulless, in all the major sports. Far from being authorities, the refs always come off as slaves to reviews, arguments with coaches, timeouts, the lot. When they make their pronouncements, they sound like a mere mouthpiece. It is almost comical then, how they will dramatically send off players at the slightest inkling of argumentativeness. Maybe it's the absurdly convoluted rulebooks, maybe the corporate nature of the leagues, but NA refereeing is one of the more prominent bland spots in local sports. Yeah, soccer referees screw up on occasion, even with the new technologies, but they still seem to inspire some genuine respect and authority.
