This past week the Detroit Pistons made the decision to let Notre Dame alum Monty Williams go while still owing him $65 million for the remaining years of his contract.  Williams made $7.9 million during his NBA playing career.  
Add on his years as a NBA coach -- with three head coaching stints in New Orleans, Phoenix and Detroit -- Monty did quite well.
NBA head coaching salaries are rarely made public. Monty was a head coach for nine seasons, before signing his huge contract with the Pistons. Let's assume that Williams made on average $4 million per year (conservative assumption) over those nine seasons as a head coach and $500,000 per season (conservative assumption) during his 7 seasons as an NBA assistant coach. This would total $39.5 million.
Williams' Detroit Pistons contract totaled $78.5 million -- add up all of his compensation in professional sports and you have:  $125,900,000 -- which places him FIRST on the all-time list of former Notre Dame student-athletes:
