First problem was the official was out of position to begin with. If he was where he was supposed to be he probably would have seen it. Not saying he would have made the right call but it is hard to throw a flag whn you are not in position.The Big 10 and its officials scrutinize/review all questionable calls. They police their own. To claim no accountability is totally bogus. Was it PI? Yes. Did the official blow the call? Not really. He called the way he personally saw it without the luxury of multiple angles and replay. Grow up boys. Mistakes happen.
