OKLAHOMA CITY (AP) — The Thunder hired Florida's Billy Donovan as their coach Thursday, hoping he will help the franchise win an NBA championship in Oklahoma City. "We warmly welcome Billy and his family to Oklahoma City," team chairman Clayton Bennett said. "He is the perfect fit for our organization and for our community, and we look forward to a long and successful relationship." The 49-year-old Donovan led Florida to two national championships, four Final Fours, seven Elite Eights and 14 NCAA Tournament berths in 19 years. He signed a one-year contract extension with the Gators in December that would have paid him an average salary of $4 million through 2020.
