Tennessee basketball on Thursday announced a three-year contract extension for head coach Rick Barnes, giving him a $1 million raise in the process.

Barnes’ three assistant coaches have received bumps in salary as well entering the 2018-19 season.

Associate head coach Rob Lanier received a raise of just under $35,000, going from a salary of $390,113 last season to a current salary of $425,000.

Assistant coach Desmond Oliver received a $50,000 raise, putting him at $275,000 annually, an assistant coach Michael Schwartz received a raise of $43,250, putting him at $275,000.

Tennessee’s staff salary pool is now $975,000, up from $846,863 last season.

Barnes was caught last February going out of pocket to give Oliver a raise he felt he deserved.

It was self-reported to the NCAA by Tennessee in October of last year as a Level III violation after Barnes “openly told his supervisors” about the payments.

The SEC and NCAA accepted Tennessee’s response to the violation and did not impose additional penalties, according to the report.

“I just felt those two positions needed to be equal,” Barnes told the News Sentinel. “They felt it wasn’t in the budget. I just said, ‘I am going to pay it myself.’”

Barnes felt Oliver and Schwartz needed the same salary when he paid out of pocket. The two are even entering the new season after the staff received raises.

“It’s equal now,” Barnes told the News Sentinel in February. “But for a year, I did it. He works his butt off. It was important to me that he knows how much we all appreciate him.”

Lanier, who coached under Barnes at Texas, and Oliver, who Barnes hired away from Charlotte, are original members of his staff at Tennessee. Schwartz was hired away from Tulsa before the 2016-17 season, replacing Chris Ogden, who left for an assistant job at Texas Tech and is now the head coach at Texas Arlington.

Barnes, after the three-year extension, is now working under a six-year deal worth $21 million and running through the 2023-24 season. He's now the second-highest paid coach in the SEC and No. 10 nationally.

Barnes is set to be paid $3.25 million for the 2018-19 season. The salary grows by $100,000 each season, topping out at $3.75 million in the 2023-24 season, the final year of the new contract.

"Tennessee is a very special place, and I believe this program is capable of accomplishing very special things," Barnes said. "I particularly appreciate the commitment that Phillip Fulmer and Chancellor Davis have made to my staff. I truly believe I'm surrounded by the best staff in college basketball. I also appreciate the way Tennessee fans have embraced the program and supported our players.

"Candy and I are blessed to have made many wonderful friends here in Knoxville, and we're looking forward to continuing to play a role in some of the remarkable things happening throughout the community."
