The new deal gives McGuire a pay increase of about $1 million per season. It links the coach to Texas Tech through the 2028 season and includes $100,000 annual raises — topping out at $4.6 million in the final season — plus performance bonuses.
Texas Tech closed the regular season on a three-game winning streak for the first time since 1995.
“We firmly believe the success our team has experienced this season is the standard for what is yet to come,” McGuire said in a statement.
McGuire joined Texas Tech following five seasons at Baylor, including the final three as the Bears’ associate head coach. He also coached Cedar Hill High School to three Texas state championships.
