I watched some of Johnny Swaim's better teams play in DMC a long, long time ago. With ~5,500 or more TCU fans and a good game, the crowd could be deafening. I hope today's students have that experience soon. Next year would be good.
Watching on TV (from Austin), I couldn't distinguish KU blue from TCU purple in non-student seats. The casual observer would probably think the crowd was predominately TCU.
It was really, really nice that KU fans lacked the enthusiasm to control the noise. I was expecting it to be the other way, particularly as their fans seem to be a lot better than TCU fans at making noise at appropriate times and being relatively quiet at appropriate times. The TV personalities commented on the few time that KU fans started chiming in, during what passed for KU runs in the second half. But the KU fans never threatened to hijack the home court noise advantage, at least by the TV appearance.
