Haines was a finalist for the Broyles Award (top assistant) in 2024 and a semifinalist for the award in 2023. During Allen’s one season in State College, Penn State, the Lions finished No. 7 in FBS in total defense (294.8), No. 8 in scoring defense (16.5) and No. 9 in rushing defense (101.9).

Allen replaced Manny Diaz as Penn State's defensive coordinator after Diaz became the head coach at Duke. PSU’s defense was one of the best in college football in 2024 and allowed as many yards per play overall as Clemson did per rushing attempt. Opposing offenses averaged just 3.1 yards a carry against the Nittany Lions.

Defensive coordinator Tom Allen is leaving Penn State after one season to take the same job at Clemson, according to several reports Monday. Allen spent the previous seven seasons at Indiana as the Hoosiers head coach before he was fired after the 2023 season. Nittany Lions coach James Franklin quickly hired him.
