Billy Gillispie Resigns as Texas Tech Basketball Coach (AP) - The Texas Tech men's basketball coach, Billy Gillispie, has resigned because of health concerns, the university said Thursday, ending a disappointing one-year run at a program he had intended to turn into a powerhouse. The university and fans had hoped that Gillispie, 52, could orchestrate a turnaround like the ones he put together at Texas-El Paso and Texas A&M. Instead, he led the Red Raiders to an 8-23 record last season. Gillispie did not immediately return a call for comment. The move came less than a month after the university announced it was looking into allegations that Gillispie mistreated players last fall. In January, the university reprimanded Gillispie and the assistant coach Brooks Jennings after a review found the team had exceeded practice-time limits. Meanwhile, Gillispie's health was apparently growing worse. Twice in a 10-day span recently, 911 calls were made from Gillispie's home. The first, on Aug. 31, led to a six-day stay in a Lubbock hospital. 11, Gillispie left for the Mayo Clinic in Rochester, Minn., where he said he received treatment for kidney problems and abnormal headaches. Gillispie's first two years as a college head coach were at UTEP in the Western Athletic Conference. He took the Miners from a 6-24 record in 2002-3 to a 24-8 mark the following season. The conference named him coach of the year in 2004, the same year he was a finalist for the Naismith Coach of the Year award - the first of three times he made the final cut.
