Mike Leach believes he is still owed $2.5 million from his time at Texas Tech. As such, he has hired an investigator to dig up information about school officials.

"We're going to get into their stuff, OK?" Wayne Dolcefino of Dolcefino Consulting said, per USA Today's Brent Schrotenboer.

"If they want to be weasels and not pay the guy, then they won't pay him," Dolcefino added. "But we're going to look under every nook and cranny. We're starting with phone records."

Leach was the head coach at Texas Tech from 2000-09 but was fired for cause because of his alleged treatment of former player Adam James while the receiver had a concussion. The coach had just signed a five-year, $12.7 million contract extension the previous offseason, but firing for cause helped the university avoid paying the remainder of the deal.
