Honestly, the thing that most people seem to be over-looking is that the original "ruling" on the field was Alabama ball at the 1 yard line. Go back and look at the replay. The head official doesn't seem sure of himself, but he definitely points in Bama's direction.
Then, of all things, he takes off the headset and announces that the ruling on the field stands (which, coincidentally, is why the stadium erupted - Bama fans aren't stupid), but then he gave Penn State the ball first and ten from the 3 yard line. Huh?
The head official must have forgotten the original call, because there's no way that there was indisputable video evidence on that replay that Dre lost control of that ball before hitting the ground at the 1 yard line. And if you pay close attention, I don't believe that there was a clear consensus among the officials, either, especially one of the younger officials...
