I seem to remember the same thing - or we could both be wrong on that.
I do have a different take - I think running the two tourneys at the same time, and hoping for "spillover" attendance is demeaning to women. Now, whether to have it in KC, or OKC, or Dallas, is another issue. There is justification for having it where support is strongest, but also to spread it around for fairness and exposure. Women's fans don't seem to want to travel much.
But having both tourneys running concurrently in the same city automatically makes the women's teams second class IMO.
"What ya wanna do now honey?"
"Well, we can always go over to the women's game."
I am going to sounds like an ***, but men's basketball is superior to women's basketball. That is a fact. Now you can take that as a slight against women you can recognize that as what it is, a fact that men are better at basketball than women. If you don't believe me go to your local gym, find 4 girls and yourself and play a team with five boys of the same age. Unless you are under 10 the boys will win as long as the games aren't played to 2.
All that said, the women deserve to be somewhere where they can be appreciated, so what if that is Joe blow saying "honey we don't have anything to do till ISU kicks off at 6, lets go watch the women play at 1." What difference does that make. And if what you say is true, isn't just as demeaning to put them in two different towns and everyone picks to only go to the men's tournament. ISU has great support for their women's basketball team, and it is great and the girls deserve every ounce of that support. But unless you are a parent, grandparent sibling or screwing one of them, don't ever think anyone is going to choose the women's tournament over the men's if all things are equal.
While men might be stronger athletes not all sports are better to watch with men on the court, field or whatever. Women's volleyball, tennis, and gymnastics come to mind. I am sure their are others.
