It is an amazing streak of 23 years. But a team like ND is on a current five year streak since Nov 2010 which includes a complete roster changeover and I suspect Baylor is also on a fairly long current streak. In contrast ND has never had an undefeated seasons, and Baylor has one, as do only two other teams. To lose two games in a row for a really good team, you have to play two really good teams in a row, or throw a complete wobbly before or after losing to a really good team, and very few teams have yearly schedules that include two really good teams in a row. What Uconn's streak really points to is that even in the 'dark days' of the 1990s and 2000s they were still a really good team even if they didn't make it to the FF.
