Since the pod system was created in 2002, the advantage for the higher seeds has been staggering.  Now let's take this a step further.  Here is the make-up of a typical Elite 8.

Expect at least 3 one seeds.
Expect at least 6 teams to come from teams that have been to the Final 4 since 1985.
Expect one mid-major.
Expect one team that does none of the above (Missouri last year).

Expect 7 teams to have an RPI below 22 (last year, the highest RPI was 13).  The last team's RPI will be below 54 and more likely to be between 23-38.

So the question becomes, who are those outlier teams that may crash the party.  Here is the short list outside of teams that I have mentioned in the Final 4 posts:

Missouri
Maryland
BYU
West Virginia
Florida
Ga Tech
Butler
