Interesting development here in the preseason. An important detail: the usual refs are locked out due to contract negotiations between the officials' union and the NFL. These "replacement officials" are, in fact, scabs being double-teamed by the union whose picket lines they're crossing and the players, who are themselves unionized. Without having watched the games, it's hard to say whether it's true that these refs were "clueless" or were just being judged ungenerously by a hostile audience.
Frankly, I'm not sure it matters, either. Union workers may or may not be better or more qualified or more diligent than non-union workers, but that isn't the point of supporting unions or the reason to despise scabs. Unions should be supported because the alternative is to hand all power over wages and workplace conditions to the bosses. We've had that situation before, and it wasn't pretty.
Sadly, these are also the circumstances under which the NFL is hiring its first female referee. It's sad that Shannon Easton has to cross a picket line to break through this glass ceiling.
