It’s time once again for our regular trivia contest before men’s basketball games: Robic’s Riddle.Assistant coach John Robic has supplied us with yet another question from the annals of Kentucky basketball history. The first fan to submit a correct answer via email to catscratches@uky.edu will receive a prize. The prize today is a pair of heavy-duty plastic UK cups that will keep drinks either hot or cold.Today’s question has to do with a rare accomplishment for John Calipari.Calipari has led three different schools (Kentucky, Memphis and Massachusetts) to a No. 1 ranking. There is just one other coach to do the same. Can you name the coach and the three schools he took to a No. 1 ranking? Again, please submit your answers to catscratches@uky.edu. We will announce the correct answers at halftime of this evening’s game, assuming we have a winner by that time.Don’t forget to tune in and watch the Cats take on Lamar at 8:30 p.m. on ESPNU.
