My only guess is that they called someone for impeeding his path towards the football, which I can somewhat see. That was a Big Ten crew, if we have to get used to this I will be angry. They don't call holding along the OLine at all. Crick and Meredith got held every single play and at times it was very obvious.
The holding was downright ridiculous today.
The interference call was horrible. Had that happened to us, we'd be up in arms. You can't go back and revise the score and determine how it would've played out, but you have to admit that the call really changed the momentum of the game.
