K.J. Costello made *quite* the SEC debut on Saturday for Mississippi State. Costello threw for an SEC record 623 yards and five touchdowns to lead the Bulldogs — a 14.5-point underdog — to a 44-34 road victory over No. 6 LSU.

LSU — which is definitely not in the same universe without Joe Burrow — didn’t score in the first quarter, and finally got on the board with a pick-six of Costello in the second quarter to take a 7-3 lead.

And the Tigers scored their first offensive touchdown when quarterback Myles Brennan somehow completed a crazy touchdown pass

But the story of the day was without Costello, a senior who spent the previous three seasons playing quarterback at Stanford. Now, Costello certainly had some help from his playmakers on offense, to go with the lack of playmaking by the LSU defense. That was shown perfectly on this 75-yard touchdown pass to Kylin Hill in the third quarter:

And in the fourth quarter, Costello made a beautiful pass to Austin Williams for a touchdown to give the Bulldogs a double-digit lead.

Costello reached 623 passing yards with this dagger 24-yard touchdown pass to Osirus Mitchell:

And here’s the Mississippi State radio call of that touchdown:

An absolutely unbelievable debut for Costello, and he should make the Bulldogs a very dangerous team in the SEC. Mississippi State will look to go to 2-0 when they host Arkansas next Saturday.
