At halftime, the Clemson Tigers lead 18-7 against the Florida State Seminoles at Memorial Stadium.

Below is an analysis of Clemson’s first-half performance offensively and defensively.

Offense:

— After their ceremonious march down the hill, the Tigers began the game by blowing the door off the hinges. Cade Klubnik found the end zone on the 13th play of a commanding six-and-a-half-minute drive. The icing on the cake? Clay Swinney squeezing past enemy lines, converting a surprise 2-point attempt to complete the “father-son special.”

— Klubnik found his deep ball. With the freedom to float passes downfield, Klubnik completed a 25-yard pass to Olsen Patt-Henry on the opening drive and a 34-yard flea flicker to Antonio Williams in the second quarter for a spectacular, diving touchdown catch. No. 2 finished the half with 135 yards, a touchdown through the air and another on the ground.

— In a game between two teams who have weathered unpredictable seasons, Clemson embodied the spirit of the unpredictable. Offensive coordinator Garrett Riley put on a playcalling clinic with a flea flicker, a trick-play 2-point conversion, pitches out of the backfield and quarterback scrambles. In a demonstration of imposed will, the Tigers took what they wanted, however they wanted it.

— The Tigers held on to the ball like a goose protecting her egg. Compared to FSU’s measly 10 minutes of possession, the Tigers held the pigskin for almost 20 minutes. Sustained drives — and some help from the defense — kept the Seminole offense off the field while also hatching an 11-point lead at halftime.

Defense:

— Following Clemson’s explosive offensive start, FSU looked for a powerful start of its own to open up the game. The first offensive drive for the Seminoles started strong with a 13-yard completion on the first play. However, Clemson quickly stopped the bleeding and forced FSU to punt after just over one and a half minutes of possession.

— After a shanked 15-yard punt by Jack Smith, FSU’s offense was set up with great field position at Clemson’s 35-yard line. A 24-yard scramble by Seminoles quarterback Tommy Castellanos put FSU in the red zone, but Castellanos fumbled on a fake handoff just two plays later. Alabama transfer Jeremiah Alexander recovered the fumble to get the ball back for the Clemson offense.

— The Seminoles’ first drive of the second quarter ended much like their last drive of the first: short and unproductive. On fourth-and-1, FSU decided to go for it, and had a man wide open along the right sideline. However, the pass was dropped, and the Clemson defense got away with one to force a turnover on downs and put the offense in good starting field position.

— Clemson’s defense allowed its first score of the game on FSU’s final drive of the half. The Seminoles went 75 yards in 10 plays in a drive that ended with a touchdown pass. The completion was reviewed but ultimately upheld, much to the disapproval of the home crowd.

— The Tigers came into the matchup allowing an average of 245.1 passing yards and 105.8 rushing yards per game. They’ve completely flipped the script through the first half, allowing just 75 yards through the air and 66 yards on the ground alongside a forced fumble and a turnover on downs. The key to the rest of the game is likely whether the defense can continue to smother the FSU offense.
