There are approximately 10 teams that have made the tournament at least 8 of the past 10 years (2010 through 2019). Then you have SBU, PSU, Duke, Towson, Navy, JMU, Stanford, UMass that have made the tournament 7 of the past 10 years, assuming I counted correctly quickly going through the brackets.

Penn State, James Madison and Duke have multiple post-season appearances for many years prior to 2010, so it's fair to include them in a list of teams that are historically top 10-15, or at the very least perennial top 20 programs.

A few surprises in this year's bracket in my opinion - expected UNC or BC to get the #1 seed after NW convincingly beat Maryland, and #8 seed seems a bit high for Michigan. ND has wins over seeded teams and seems more deserving in spite of the Duke loss, but their extremely weak out of conference schedule combined with the Duke loss probably hurt them.
