There are four different camera views on the play. What doesn't appear in the extremely short clip, is what follows. According to comments made today ....and I have my doubts as to the source. The SEC stated there was no conclusive evidence that the ball was touched.
When the ball passes number 8, he turns to pursue the ball going into the endzone, then stops before he reaches the endzone. The side official blew his whistle. There is no "immediate" coverage consideration under the whistle and replay issue. It's not immediately covered.
Remember, this is a kickoff. Coverage from Old Miss is not fast enough to sprint to an immediate cover at the goal line. There is only one player in entire stadium capable to get there and he's wearing number "1" in white. A world class sprinter timed at low 10's in the 100 yard dash in high school. If it weren't for the pandemic ..he would have been in Tokyo competing.
I doubt the supposed SEC version of no compelling evidence the ball was touched. I say that because it was clear the crew made a clear mistake in the illegal, backward panic pass vs. Arkansas. The snap was fumbled ( direct snap) touched the ground, QB picked up the ball, then spiked it behind his feet...the White blew his whistle because he ignored the first rule of "expect the unexpected" White Hat was caught off guard expecting same ole, same ole, blew his whistle and was caught with his pants down...crew echoed the whistle as the ball bounded away from the QB, was touched by Arkansas, bounced away from the touch, touched the "C" official's foot, then was recovered by Arkansas.
If it was touched, a whistle stopped "8" from chasing the ball in the endzone. Why not simply state "A whistle blew the play dead. Before the ball is recovered in the endzone, officials are signaling touchback.
