Outside of the Utah Valley game and the alabama A&M which saw some Thanksgiving travel single seat purchases, I am not seeing too much fluncuation in attendance for basketball games.  I would imagine you are pretty much seeing the people that have season tickets being counted towards attendance and not much more than that.
