When Quinn was celebrating, he sort of, almost, spiked the ball in the end-zone. I think the ref was trying to tell him not to force his hand into unsportsmanlike.
The "how to spot the ball" thing was just amateur hour. I don't think Sark wanted it reviewed. I think he was trying to point out the obvious error so they didn't look stupid (and cost Texas 4 yards and a sack). The near side line judge got taken out on the play, but I gotta believe more than one official can spot a ball.
It took the officials 5 minutes to come to that conclusion. Meanwhile the LHN never referenced it. They lauded Wyoming coach Craig Bohls for the entire time.
