This one was a stinker.

No. 5 Auburn steamrolled No. 15 LSU 41-7 on Saturday night in Jordan-Hare Stadium, ruining the debut start of LSU’s true freshman quarterback and gashing what appeared to be an unfixable defense.

Gus Malzahn’s high-flying, up-tempo offense poured on nearly 400 yards — in the first two quarters — and Auburn soared to a 31-7 halftime lead in a crushing victory in front of a rowdy sellout crowd of 87,451.
