If memory serves, I think Dave Witvoet was the replay official for the Nebraska game. He was the ref that essentially screwed us against Michigan in 2005 (probably because he's a Michigan alum and had Wolverine shit all over his office). So yeah, it wouldn't surprise me in the least if he tried to screw us.
When you look at the two major plays in question, the Ragani catch/no catch and the ISM targeting/no targeting, it blows my mind how both of the calls were over-turned. First off, there has to be "clear and convincing evidence" to overturn a call on the field. I'd like to know how there was any evidence to indicate that Ragani's catch should be overturned. By every definition, it was a catch. He established control before going down, his knee and elbow hit and he still had control. Only when he rolled over after establishing all criteria did the ball then come out.
On the targeting overturn, the rule clearly states that an excessive blow to the head or neck area of a defenseless receiver by the forearm, shoulder, or helmet of the opposition is targeting. There's no question that ISM was in a defenseless position when he caught the ball as he was completely stretched out. There is no question that the defenseman hit ISM in the helmet with his shoulder. And there's no question it was excessive based on how severe his head snapped forward and his immediate reaction in grabbing his head.
If I'm Gary Barta, someone at the B1G office owes an explanation for the overturn of those two calls.
