Tom Allen became Dabo Swinney's fourth defensive coordinator hire. Allen explained Wednesday why he left Penn State after one season.

CLEMSON, S.C. — Clemson has hired Penn State defensive coordinator Tom Allen for the same role with the Tigers, a move that was finalized by the school’s Board of Trustees Compensation Committee.

Allen, the former Indiana head coach and Penn State defensive coordinator, will make $1.9 million in total salary in 2025, $2 million in 2026 and $2.1 million in 2027. That makes him the highest paid assistant on staff, jumping offensive coordinator Garrett Riley (annual salary of $1.75 million).
