Make the women's tourney a 2 weekend event.
Weekend #1: 8 sites (each) host an 8-team regional. Make the regionals "truly" regional so attendance will swell. Only teams seed 6, 7, and 8 (the bottom 24 teams in the 64-team tourney) would have to play faaaarrrrr away from home. 4 games played on Friday, 2 on Saturday, 1 on Sunday.
Weekend #2: The 8 regional champs move on to the Elite 8 site. Once again, 4 games played on Friday, 2 on Saturday, National Championship game on Monday.
The key to this format would be to make sure that the regional seeds 1-5 are located within a 10 hour drive of their campuses, thus increasing the likelihood that attendance would increase. Having fans from 8 teams converge on one site also helps attendance for all of the games at that site
Don't tell me the girls can't play 3 games in 3 days. They do it in high school and AAU.
One issue would be competing for airtime with the men's tourney, but that COULD be solved by shifting the women's season to begin and end 2 weeks earlier than at the present. This move would also present an opportunity for the networks to air women's games for 2 weeks before the men get started.
A second issue is "the product" wouldn't be as spread out as the NCAA supposedly prefers, but this could be remedied by restricting a city to hosting a regional only once in a 3 year period. This, I believe would actually showcase the sport over a wider area in the long run. Face it, Knoxville, Storrs, and a few other cities have hosted regionals annually for so long that they think the regional is an entitlement.
