Clemson offensive coordinators Tony Elliott and Jeff Scott have joined the millionaire coaches club.

Elliott and Scott were among the 15 Clemson football assistants and staff members for whom the Clemson University Board of Trustees Compensation Committee approved pay raises Friday morning.

The coaching staff was rewarded with raises for the fourth consecutive year after steering Clemson to its fourth consecutive Atlantic Coast Conference title and its second College Football Playoff national championship in three years.

Elliott and Scott received a 17.6 percent raise that increased their salaries to $1 million each for the 2019 season. Last year, 21 college football assistant coaches earned at least $1 million, according to figures compiled by USA TODAY Sports.

That included Clemson defensive coordinator Brent Venables, who signed a five-year, $11.6-million contract one year ago that increased his salary by approximately $500,000. Venables earned $2.2 million last season, the second highest figure among assistants included in the USA TODAY Sports compilation behind only Louisiana State defensive coordinator Dave Aranda ($2.5 million).

Venables was the only one of Dabo Swinney's 10 on-field assistants who did not receive a pay raise Friday, but Venables did receive a $200,000 retention bonus.

Venables' salary will remain at $2.2 million next season, but it will increase to $2.4 million in 2020.

Florida State defensive coordinator Harlon Barnett is the only other ACC assistant with a salary of at least $1 million. Long-time Virginia Tech defensive coordinator Bud Foster earned $975,000 last season.

Last season, Clemson's total assistant pay was approximately $6.8 million, the second highest total behind only Ohio State, who paid its assistants $7.4 million. In 2019, Clemson will pay its 10 assistants $7.4 million.

That excludes any performance incentive bonuses the coaches may receive for repeating as conference or national champions.

Clemson head coach Dabo Swinney earned $6.2 million last season, before earning more than $1 million in performance incentive bonuses this year.
