Notre Dame beat UCONN by double figures when they had both Shea/Svet....
Notre Dame was really really REALLY good that year. They had an incredibly experienced starting 5 and everyone knew their role. Riley was the most dominant player in the nation that season, Ivey was arguably the best point guard that year, Ratay the best shooter and Siemon/Haney were strong supporting players who put up double figures most nights.
UCONN, on paper, was the nation's best team in 2001. They returned everyone from their outstanding 2000 squad, plus added in DT. In one of the first games of the season they looked unstoppable, clobbering Georgia by 27 at home. That said, they never had the same cohesiveness and fire that the 2000 and 2002 squads did. In 2001, Ralph was a shadow of the player she was in 2000, Taurasi had an up and down freshman season, and besides Cash, no one made big strides from 2000 to 2001. With a full lineup, UCONN lost to Notre Dame in a game that wasn't very competitive, and lost a great game against Tennessee who was without Catchings (although in UCONN's defense, Svet went down that game.)
In regards to who would've won if both teams were at full strength in the Final Four, my money would've been on Notre Dame since they had the more experienced roster, played with a greater sense of urgency than Connecticut and beat UCONN soundly when both teams were at full strength.
I haven't read this book in years, but all UCONN fans should read this book:

The author followed UCONN for a season and provides a great inside look at the ups and downs of the 2000-01 Huskies.
