Mississippi State quarterback K.J. Costello has been named the Walter Camp Offensive Player of the Week, the Walter Camp Football Foundation announced on Sunday.

Costello’s performance made for a successful debut for Mike Leach and his patented Air Raid offense. During the Bulldogs’ 44-34 win over LSU, the Stanford transfer threw for an SEC record 623 yards, going 36-of-60 while adding 5 touchdowns. He becomes only the 3rd Mississippi State player to win the honor.

“[He] wasn’t perfect…[but] he kept swinging,” Leach told reporters following the game at Tiger Stadium in Baton Rouge. “I thought his composure in this game was outstanding.”

Three different Bulldogs receivers broke the 100-yard receiving mark, including Osirus Mitchell’s game-high 183 yards.

Mississippi State hosts Arkansas in its home opener on Saturday. Kickoff from Davis Wade Stadium is set for 7:30pm ET.
