Mississippi State quarterback KJ Costello had the most impressive debut of any SEC quarterback in history.

The Bulldogs signal caller threw for an SEC record 632 yards and 5 touchdowns in his very first game. We’re still shaking our heads, and yeah, that MSU Air Raid is much better than advertised.

Costello was impressive on so many levels during MSU’s 44-24 upset over LSU, and it even got Super Bowl Champion and MVP Patrick Mahomes’ attention.

Mahomes’ reaction is too perfect.
