NASHVILLE, Tenn. — The celebration was on track to begin early in Nashville on Saturday afternoon as Texas commemorated its first true road game as a member of the SEC. The Longhorns — buoyed by a burnt-orange contingent of fans that comprised half of FirstBank Stadium — had run off 21 consecutive unanswered points and were poised to add even more just before halftime. It looked like they were on track for a palate-cleansing day of redemption following last week’s 30-15 loss to Georgia.
