The Washington Post, through a freedom of information act request, received and published summaries of each assistant's contract (other than Gary Crowton's which wasn't received?).
Of note, each of the contracts is three years in length; however there is a clause in each that stipulates that "termination shall occur in the event and on the day that Randy Edsall's service as the Head Coach of the Team shall end."
Defensive Coordinator Todd Bradford annual compensation including base pay and guaranteed bonuses from radio / tv, personal appearances, fundraising and apparel / equipment endorsements totals $350,000.
Most of the other assistants are in the $170,000 - $250,000 range.
The lowest paid full time coach is John Dunn, tight ends coach / recruiting coordinator who makes a combined $150,000.
Andrew Wilson, head strength coach, makes $140,000 while Alan Weber, assistant strength coach, makes $75,000.
Fran Foley, director of football operations, makes $110,000 (hey, how come the Ops guy doesn't get an apparel deal?).
Salary and bonus info for each of the assistants is available here.
