The key: Sophomore running back Derrius Guice served notice that LSU wouldn’t miss injured starter Leonard Fournette too much with a scintillating 42-yard touchdown run.
The key: Guice, who briefly went to the locker room early in the quarter after his second touchdown run, galloped 37 yards untouched for his third touchdown of the first half and a 21-0 halftime lead. He had 13 carries for 136 yards before halftime.
The key: LSU owned more than a 6 1/2 -minute advantage in time of possession during the third quarter and had a 20-minute edge through three quarters. Missouri only had possession for 17:27 compared to 42:33 for LSU.
The key: Mizzou avoided the shutout when senior wide receiver Eric Laurent, who started his career as a walk-on quarterback, tossed a 21-yard touchdown pass to sophomore starting quarterback Drew Lock.
Three three-and-outs to start the game weren’t ideal, and it scarcely got better from there. Missouri finished with 265 total yards in a performance worthy of 2015.
Missed tackles piled up early, and LSU shredded Mizzou’s defense on the ground, while coverage struggles on underneath routes persisted.
Chris Black almost muffed a punt, but punter Corey Fatony averaged 44.1 on eight punts, including six downed inside the 20-yard line.
Mizzou’s offense wasn’t able to exploit any aspect of LSU’s defense, and J’Mon Moore touched off a sideline-clearing shoving match as halftime arrived by tapping LSU senior cornerback Tre’Davious White in the face mask with the ball in his hand after a meaningless 16-yard catch.
Player of the game: LSU junior running back Derrius Guice averaged 9.6 yards per carry, racking up 163 yards and three touchdowns in 17 carries with an array of video-game moves.
Reason to hope: Missouri can’t lose next week as the team enters a bye week, and first-year offensive coordinator Josh Heupel’s side avoided a goose egg.
Reason to mope: Some reporters declared that Mizzou’s offense was legit, capable of scoring against anyone. LSU disproved that theory, outgaining Mizzou 357-110 and owning a 19-5 edge in first downs during the first half.
Looking ahead: The road doesn’t get any easier after the off week with a trip to “The Swamp” for a meeting with reigning SEC East champion Florida on Oct. 15.
