In a shocking turn of events, longtime Kentucky men's basketball head coach John Calipari is expected to leave the program after 15 seasons to take the job at SEC rival Arkansas. \xa0ESPN reports that the 65-year-old Calipari should be signing a five-year deal with the Razorbacks at some point early this week. \xa0Since taking over at Kentucky, Calipari led the storied program to four Final Four appearances and the 2012 national title. \xa0He signed a 10-year deal with Kentucky in 2019 that had a clause in it that would allow him to remain a paid ambassador for the school once he retired. \xa0Calipari will take over for Eric Musselman, who was hired by USC on April 4th.
