Dak Prescott held the record for passing yards at Mississippi State. That was until K.J. Costello, Mike Leach and the offensive genius’ offense took the field for the Bulldogs.
Costello became the first SEC quarterback to throw for 600 yards in a game as Mississippi State shocked defending national champion LSU, 44-34, Saturday in Death Valley.
Prescott, the Dallas Cowboys’ QB, held the school record with 508 yards against Arkansas in 2015.
Costello, who transferred from Stanford over the last offseason, threw for 623 yards and five touchdowns on 36-of-60. In 29 games for the Cardinal, Costello threw for 6,151 yards over three seasons.

Costello broke the mark of passing yards by an LSU opponent at Tiger Stadium held by Rex Grossman and wasn’t close to being done.
Mississippi State QB K.J. Costello's 470 pass yards (and counting) are the most by an opponent in LSU Tiger Stadium history.
The previous high by an LSU opponent at Death Valley was 464 by Florida's Rex Grossman in 2001.
