The NCAA tourney expanded to 64 teams in 1985. Thats 35 years ago. That means there have been a total of 140 Final 4 participants over that time.

There are around 350 NCAA D1 teams. So at MOST 40% of the teams could have made the Final 4. But we know some teams have made it multiple times.

I'm wondering how many different Schools have made it? What's your guess?

I wonder how many of the total spots were filled by the top 5 teams with the most Final 4's? Any guesses on this one?

Same EXACT thing can be said about #1 seeds. How many different teams have pulled that off?

I'll be researching this over the next day. Will be interesting to see if any quick guesses come close to the actual answers....
