Subconscious bias by some officials and conspiracy by the league are completely different. And there is an obvious bias by officials not to call major penalties in championship games--especially at the end of games. The non-call last year was a bridge too far and needed to be called. The non-call OPF at the end of the Minnesota game was not nearly as egregious; had I been the official, given the circumstances, I don't believe I would have called it.
