Clemson's Surging Secondary Faces a Much Bigger Test in Miami's Darian Mensah

Clemson just made life miserable for one of the ACC's most productive quarterbacks.

Saturday in Death Valley, the degree of difficulty is about to increase.

Miami quarterback Darian Mensah will arrive having completed a remarkable 94-of-106 passes for 1,211 yards and 14 touchdowns without an interception through four games, showcasing what Mario Cristobal and the Hurricanes liked about the former Duke and Tulane star.

Mensah’s 88.7 percent completion rate is absurd.

He continued his torrid start Saturday against Central Michigan, completing 23-of-27 passes for 338 yards and three touchdowns in Miami's 52-3 victory. He also ran for a score as the now fourth-ranked Hurricanes improved to 4-0. 

Clemson's challenge will be finding a way to disrupt an offense that hasn't given opposing defenses many opportunities.

The encouraging part for defensive coordinator Tom Allen is that the Tigers just showed they can make a productive passing game uncomfortable.

Cal entered Friday night's matchup averaging 321.7 passing yards per game. Clemson held the Golden Bears to 145, with starting quarterback Jaron-Keawe Sagapolutele managing just 119.

Clemson challenged Cal's receivers at the line of scrimmage, forced Sagapolutele to hold the football, and allowed its defensive front time to create pressure. The result was two sacks, two interceptions, and only three points surrendered by the defense.

“We disrupted him, did a good job covering,” Dabo Swinney said Sunday. “We really affected him.”

That formula could become even more important against Mensah.

Clemson's secondary is led by junior Ashton Hampton, who entered the season as the most experienced returning member of the group. Hampton already has an interception this season and matched his career high with three pass breakups against Cal. 

But one of the biggest developments in Allen's defense has been the emergence of Penn State transfer Elliot Washington II.

Washington played under Allen at Penn State in 2024 before reuniting with him at Clemson this season. After intercepting a pass to seal Clemson's comeback victory over North Carolina, Washington picked off Sagapolutele twice at Cal.

Against Miami, Clemson will need more than good coverage.

Mensah's efficiency makes disrupting the timing of the Hurricanes' offense critical. Clemson's defensive front did that against Cal, with London Merritt recording his first sack as a Tiger and Jeremiah Alexander and Champ Thompson combining for another.

Swinney called Merritt's performance his best since arriving at Clemson and pointed to the Tigers' ability to make Sagapolutele uncomfortable.

Mensah presents a considerably different challenge.

He threw for 3,973 yards and 34 touchdowns at Duke last season before transferring to Miami, and Clemson already knows what he can do in Death Valley. Mensah threw for 361 yards and four touchdowns in the Blue Devils' 46-45 victory at Clemson last November.

Now he's returning with an even more explosive collection of weapons.

Malachi Toney has been Mensah's primary target, catching 34 passes for 564 yards and six touchdowns through four games. Miami's running game provides another problem; with Mark Fletcher Jr. expected to return from injury, he averages 6.4 yards per carry, and Javian Mallory averages 9.0.

That combination makes it hard to sell out to stop Mensah.

Clemson's defense has improved significantly since allowing 51 points in the season opener at LSU, but Saturday will provide a much more revealing test.

Hampton and Washington have given Clemson reasons to feel better about its secondary. The defensive front showed at Cal that it can disrupt a quarterback's rhythm.

Against Mensah, Clemson may need both.

Because through four games, nobody has found a way to make Miami's quarterback miss very often.
