Florida State defeated Louisville 16-6 in the ACC Championship Game on Saturday night.

It was a tough night for Florida State’s offense, but the Noles’ defense came through in the end. The Seminoles limited Louisville to just 188 yards of offense on the night.

Brock Glenn made his first career start in place of Tate Rodemaker, who was out with a concussion. Glenn struggled, but managed the game — and limited mistakes — well enough to keep the Noles in the driver’s seat for the entire game.

Here are 3 takeaways from Florida State’s win:

The defense is peaking at the right time

This was arguably Florida State’s best defensive performance since its Week 1 win over LSU. Louisville entered the night with the ACC’s third most-efficient offense on a yards-per-play basis with 6.57.

FSU completely shut the Cardinals down. Jack Plummer, who led the ACC in passer efficiency rating during the regular season, had by far his worst game of the season. Plummer went 13-of-36 for only 111 yards on the night. Plummer also took 7 sacks in the loss.

After a blocked punt, Florida State looked like it may surrender the lead for the first time all night in the 4th quarter. But linebacker Tatum Bethune made the play of the game, picking off Plummer in the end zone to end the threat.

FSU’s defense slammed the door on Louisville’s final 2 possessions. The Cardinals lost 11 yards on 8 plays to close out the game.

The offense struggled

Perhaps it was to be expected, but Florida State’s offense didn’t have much going in this game. Glenn completed 8-of-21 passes for 55 yards. FSU’s rushing offense averaged just over 4 yards per carry.

But the Noles did get a couple of big plays to set up their touchdowns in this contest. A 73-yard run from Lawrance Toafili put the Noles in position to score their first TD of the night in the second half. Another sustained drive in the 4th quarter allowed FSU to tack on another field goal to make it 13-6.

College Football Playoff statement

Florida State is now 13-0. However, with the other teams who are still in the mix for a College Football Playoff berth, the Noles may still have to sweat out the final rankings reveal on Sunday.

FSU’s offense has not been up to par since Jordan Travis went out with a season-ending injury. However, the Noles also did not have Rodemaker available in this game — who led FSU to a 24-15 win over Florida on the road last weekend.

If FSU is left out, it would be an unprecedented decision from the College Football Playoff selection committee. No undefeated power 5 champion has ever been left out of the top 4 before.

The final rankings will be revealed at 12 p.m. ET on Sunday afternoon on ESPN.
