Brackets are fun - not just filling them out and losing the office pool - but following the actual brackets as they play out. Some teams get lucky. Some teams get screwed. But in the end, four teams are selected because they went a combined 16-0.
Still, these things are guided by those same brackets which can settle a team's fate seemingly at random. Double digit seeds don't make the Final Four, and in the event they do it's huge news. The last four standing are overwhelmingly the teams with good offenses and defenses. All the 1s and 2s might not survive and advance four times, but a good number of them do. Even the low seeds which make the Final Four can often be described as poorly seeded, at least in the eyes of Vegas.
There is a pattern to the teams which survive the randomness, and that pattern is described by efficiency numbers. How efficient is their offense? How efficient is the defense? The better teams do in those two questions, the better chance they have of surviving, especially once they cut down the Regional Final nets and move on.
So how do these four teams match up with the teams from the past? What can we glean from the numbers?
