Quarterback Spotlight: Nussmeier Returns, Klubnik Settles In

A key storyline centred on Garrett Nussmeier, LSU’s fifth-year senior quarterback, who opted to return instead of entering the 2025 NFL Draft. This decision brought narrative weight to his 2025 campaign—often described as “unfinished business” for the Tigers. (SI, Yardbarker, The Times of India, Reuters)

Nussmeier also received the honour of wearing LSU’s prestigious No. 18 jersey, reserved for players who embody leadership and selflessness. He became the first LSU QB since Matt Mauck to don the number—a symbolic choice that inspired optimism for the program. (And The Valley Shook, ClutchPoints)

Meanwhile, Cade Klubnik stepped into his third year as Clemson’s quarterback, tasked with leading the offence against an experienced LSU defence. Analysts favoured his deep-ball ability and Clemson’s offensive cohesion. (Covers.com, College Football News, Capper Reviews)

The Game Unfolds: Tight, Defensive, and Turnover-Heavy

Final Score: LSU 17, Clemson 10

• Defence Dominates: In the second half, LSU’s defence shut Clemson out completely. Standouts like Harold Perkins and transfer Mansoor Delane, who added a key interception, anchored one of the most imposing defensive efforts of the weekend. (And The Valley Shook)
• Game-Winning Drive: LSU’s offence broke through late. Caden Durham scored a third-quarter touchdown, and in the fourth, Nussmeier found Trey’Dez Green for the go-ahead score, continuing LSU’s tradition of late-game poise. (And The Valley Shook)
• Controversy and Resilience: A potential game-sealing catch by Clemson’s Barion Brown was overturned—creating drama in the closing moments. A missed field goal by LSU could have handed momentum back, but the Tigers held strong, stifling Clemson’s final drives. (And The Valley Shook)

This marked Brian Kelly’s first-ever season-opening win at LSU, ending a six-year trend of disappointment on the first weekend. It spoke volumes for the program’s direction under his leadership. (And The Valley Shook, Reuters)

Why This Win Matters for LSU and Nussmeier

For LSU, this victory not only ends a stigma of bad openers but also sends a message that their 2025 roster is battle-ready. Kelly emphasised transparency, consistency, and integrity heading into the season—and this win showcased the team’s commitment to those ideals. (Reuters)

For Nussmeier, this moment reinforced his decision to stay: his experience, leadership, and performance in a high-pressure environment position him as a legitimate Heisman Trophy contender and potential NFL first-round pick. Scouts have even compared his play style to Tony Romo and Brock Purdy. (The Times of India, SI, PFSN)

What’s Next for the Tigers

• Clemson’s Redemption Arc: The loss sets a difficult tone for Clemson at Death Valley. Dabo Swinney’s squad must recalibrate quickly—especially in the trenches, which LSU’s pass rush exploited late. (Shakin’ the Southland, College Football News, Big Al’s)
