Sometime over the summer I will gather all the numbers available and use 14 or 15 metrics to calculate the greatest teams of the modern era. The obvious question, of course, is when does the modern era actually begin?
Here's a little more info on schools leaving conferences. As many know, 1975 is the first time we actually saw at-large bids in the tournament. No conference had more than 1 at-large bid, however. And 9 of the 16 at-large bids in 1975 went to independents. As the field expanded, schools were figuring it out that there was less opportunity to make the tournament if you're not aligned with a conference. In 1979, there were 68 independents. By 1980, there were only 21. Most notably, that's the year where the Big East was formed. In that same year, only 3 of the 23 at-large bids went to independents.
