From Mechelle: Same venue, new story lines in Raleigh: Baylor, Louisville, Maryland and Vanderbilt all seek dates in Elite Eight

The last time I was in North Carolina's capital city for the NCAA tournament was two years ago, in March 2007.

I've been back here several times since, most recently in January at the funeral service for NC State coach Kay Yow. But returning to the RBC Center, which was a host site for the NCAA first and second rounds in 2007, reminds me of how much can happen in so relatively short a period as 24 months, and how that plays into the regional games we'll see here in 2009.

Saturday, No. 2 seed Baylor meets No. 3 Louisville (ESPN, noon ET), followed by No. 1 Maryland versus No. 4 Vanderbilt (ESPN, 2:30 p.m. ET). Two years ago, all four of those programs lost in the NCAA tournament's second round.
