Clemson's season appears to be moving from bad to worse, as the Tigers ended the first quarter against Duke trailing 21-7 at Memorial Stadium.

The disastrous start comes immediately after a bye week that Head Coach Dabo Swinney had labeled a "much needed" reset for self-scouting and fixing what he repeatedly called "football stuff." Earlier in the week, Swinney had emphatically defended his program's foundation but placed the team's struggles squarely on his staff, calling the season an "absolute coaching failure" and insisting, "We can coach our way out of it."

That coaching fix has not materialized. The Clemson defense, under new coordinator Tom Allen, is struggling mightily. The unit was completely overwhelmed, allowing Duke to gain an alarming 199 total yards on just three possessions. The "horrific first quarter" for the defense was capped by a 20-yard touchdown pass from Duke QB Darian Mensah, who hit a wide open receiver on a post route for the 21-7 lead. This type of explosive play is exactly the kind of execution breakdown in "proper angle" or "playing over the top" that Swinney had insisted his staff would correct.

The offense provided little relief, managing one touchdown but also logging two three-and-out drives. The home crowd's frustration with the performance was audible, with a "scattering of boos" reported at the end of the quarter.

Tensions are visibly erupting on the Clemson sideline. Safeties coach Mickey Conn was seen flipping out on Clemson defensive coordinator Tom Allen, jumping up and down and screaming and throwing the headset around. Immediately after the tirade at his fellow coach, Conn was seen getting on player Hanafin as he came off the field. The public sideline meltdown provides a stark visual for the internal frustrations as the "coaching failure" Swinney described continues to unfold in real-time.
