No. 6 LSU entered Death Valley on Saturday afternoon in its first game since winning the national championship with the goal of proving to the world that there wouldn't be a big drop off despite massive roster and coaching turnover. The Tigers left with their tails between their legs as the first defending champion to lose its next game since Michigan in 1998. Mississippi State steamrolled LSU 44-34 in a game that saw Bulldogs quarterback KJ Costello set SEC records against a defense that had no answers for him. Costello was 36 of 60 for 623 yards with five touchdowns and two interceptions. Those 623 yards set a single-game SEC record and made Costello the first quarterback in league history to top a 600-yard mark. It was the 11th-most yards passing registered in FBS history.
