A lot of the MCBB schedule is dictated by made-for-tv matchups. You see this a little on the women's side (Baylor and UConn, UConn and Stanford so early in the season) but not nearly as much. The men's side has also developed "Conference Rivalry" series, such as the ACC-Big10 matchups, which are also made for TV, pretty much. I think on the women's side a lot has to do with teams not wanting to schedule each other, or not wanting a home-and-home series. Once you get into conference play a lot of teams don't want to schedule non-conference opponents, so that limits the scheduling possibilities also. It's very difficult to build an OOC schedule years in advance because you don't necessarily know who the top teams will be...UConn scheduled UNC for years, and then UNC stopped the series because it was such a beating. Now I would love to see that matchup.
