If you had been coaching HS ball two years ago and gotten a really nice raise to become an OC at a big time school, and then after two years they offered to give you a raise of $1 million per year to make you the highest paid assistant in college football, I'd say you'd be pretty pumped. Plus if his offense is ranked in the top 5-10 the pay automatically escalates to keep him among the top two or three highest paid OC's in college football if salaries continue to skyrocket. So no real risk unless he really doesn't like the place, which I'm pretty sure is not an issue.
