Here is one of the other Illegal Formation calls from the Miami game. We clearly do not have a WR on the line on the right side of the formation. It was the same way for BYU. So there may be more being called. But the assumption seems to be that the refs are just calling it more. It seems to me that we just aren't as good at getting lined up in the correct formation.
I'm not saying we are lining up correctly. I'm saying MAYBE they're calling it more.
The question is, have they always called this and we've always lined up correctly before, or is this a new focus for officials this year? It isn't only Nebraska they're calling it on; they called it on BYU more than Nebraska in the first game (twice for them, once for us).
