Totally agree. The insight I get is how inept he was when he was head of officiating. The whole point of replay was to change egregiously bad calls...there has to be insurmountable evidence. Pereira is always giving some half-assed opinion like "It looks like the ball might have come out", and then he concludes "They have to overturn this". NO, they don't! The evidence isn't conclusive.
On a side note, Mike Pereira is my wife's 2nd least favorite person, behind Tony Kornheiser.
