Every time Kansas State has defeated visiting Kansas at Bramlage Coliseum in Manhattan, Kan., its fans have gone bonkers. They poured onto the court in 2008, and Michael Beasley climbed on top of the scorer’s table. They rushed the floor again in 2011 after Jacob Pullen’s epic, 38-point performance. For that to happen when No. 8 Kansas (18-5, 9-1 Big 12) visits tonight ( 6 p.m., ESPN), unranked Kansas State (16-7, 6-4) will need to do something it hasn’t done this season: Beat a high-quality opponent on fewer than three days of rest.
