This is BS and the conference should be ashamed.
Officials can certainly pick up a flag after the fact. Nobody is disputing that.
What makes this so egregious is the penalty was announced, the chains were moved, ball spotted, and both teams were lined up AND THEN they reversed the call, and it only happened because fans threw beer cans on the field and stopped play. If play wasn’t stopped due to the fans it wouldn’t have been overturned.
And it is even more shameful the official in the booth shilling for the officiating tried to explain it and say it was a good job. It really is disgraceful all around if we are to believe that officials don’t make biased calls and just make mistakes, the conference needs to own the mistakes when they happen.
