It's been a rough couple of weeks for NFL officials.
The coaches are angry, from Super Bowl winners Bill Belichick and Mike Shanahan to the not quite as successful Bruce Arians and Mike Munchak.
Fans are upset, too, about calls they see and don't see, explanations they get but don't understand. Commentators are even wondering if the replacement officials have returned to the NFL.
Flags fly and everyone wonders why. Flags don't fly and everyone wonders why — but even more loudly.
