Since the inception of the Coaches' Poll in 1999, the #1 ranking in the various weekly polls has been held by only a select group of teams. Through the postseason poll of the 2002 season, the teams and the number of times they have held the #1 weekly ranking are shown below. The number of times a team has been ranked #1 in the postseason poll (the national champion) is shown in parentheses.
In 1999, the results of a postseason poll, if one was conducted, are not known. Therefore, an additional poll has been presumed, and the #1 postseason ranking has been credited to the postseason tournament champion, the Northwestern Oklahoma State Rangers.
