This chart shows the progress of each seed number in each of the four regions by year (1990-2001). Use the key below to determine the meaning of the symbols used on the chart. The symbols indicate the farthest achievement of that team, so for example, although a team may have gotten to the Sweet 16 before they lost, only a "16" is listed. Even though they also made it to the round of 32, a "32" is not listed.
