I return you to the video in which NBC clearly shows the ball never touched before the clock went zero:
It's a different video, but it's the same thing I showed before. The relevant replay starts at about 10 seconds or barely 11.
I have screenshotted the relevant situation.
If you blow it up big enough, you can see the ball, just past the goalpost support and not touched by any player on either team, in or out of bounds. The clock clearly reads triple-zero.
Why am I so precise?
Because the Big Ten Conference is officially claiming this did not happen. (Again, I have to link the video instead of just embedding the Tweet for a few more days.)
The Big Ten has an official position that THAT SAME CLOCK read 0:01. Watch the video in the link.
Someone has just committed sue-able malfeasance. Because either NBC is trying to manufacture something which is not the case to manipulate the game on their end (which probably is NOT legal, in the face of the Big Ten doing otherwise -- in the infinitesimal chance the Big Ten is not lying through their teeth), or NBC is being thrown under the bus by the Big Ten and being so accused.
If the Big Ten is telling the truth (and I do not believe they are), they are telling you you can never trust another NBC telecast, at any level. If I'm the Big Ten Conference at that point, I want a new broadcast partner, first available opportunity.
For the record, I believe the Big Ten spliced the video.
