USAToday has followed up it’s 2010 College Football Head Coach salaries study with a look at assistant coach salaries.

In 2010, 132 assistant coaches are making $250,000 or more, up from 106 last year. 26 coaches are making over $400,000, up from 13 coaches last year. And 4 assistants are making over $700,000 per year.

The higher salaries can likely be attributed to the recent trend of schools hiring a “coach in waiting”. Schools like Texas paid a high salary to assistant Will Muschamp to keep him at the schools for years. Muschamp did decide to leave Texas for Florida to be it’s head coach. West Virginia recently went down the “coach in waiting” path in hiring Dana Holgorsen, who will make $800,000 next year before taking over as head coach in 2012.
