I'm staying at a relatives house this week so I get to watch NFL Network and just saw the Official Review segment where they look back at controversial calls and the head of officiating explains it. I'm curious to know whether they ever admit a blown call. Does Perreira find a way to justify every call made to defend the officials? Or maybe they don't even address the ones that were clearly wrong? Could be very annoying as a viewer to always hear that officials are human and will make mistakes but no one will ever own up to it.
