SEATTLE — The reason for Nick Holt's departure from USC to become Washington's defensive coordinator now seems evident.

The university said Tuesday that Holt could make up to $2.1 million as part of a three-year contract with the Huskies.

Holt will make $600,000 his first year and $650,000 in the next two seasons. He was also given a $200,000 retention bonus paid upfront, but that would have to be returned to the school — on a sliding scale — if he leaves before the end of the contract.

The deal makes Holt the highest paid assistant in Washington history. New offensive coordinator Jim Michalczik, who came from California, will make $350,000 per season as part of a three-year contract.
