On Saturday, it will be lights, camera, action at Rupp Arena. The No. 3 Cats (23-1, 8-1 Southeastern Conference) will take on Tennessee (18-5, 6-3 SEC) at 9 p.m., but the festivities will begin in the morning when a sellout crowd at Rupp Arena watches ESPN broadcast their live weekly college basketball pregame show, College GameDay. “I can’t believe it,” said ESPN college basketball analyst Jay Bilas referring to the expected size of the crowd on Saturday. “I’ve never heard of anything like that. It just shows what fervor there is for basketball here and how great this place is.”
