While many programs might tout themselves as one of the top NCAA Division I dynasties, a case could legitimately be made for several programs, including Iowa wrestling, Arkansas men's track and field, North Carolina women's soccer, UCLA men's basketball and Indiana swimming.

However, considering the wide range of all variables -- different eras, differences between sports, length of season, emphasis on individual performance and rule changes -- it's impossible to definitively say which is the top dynasty of all time.

All that said, here's a look at our five greatest programs in NCAA history, listed in order based on number of NCAA titles:
