I would love to see Mizzou play in St. Louis as a #2 over a #1 elsewhere, but I think that is gonna be tough. If Kansas wins out they should be a #1 in St. Louis. In that case I don't think Mizzou would be a #2 in St. Louis. Some unwriten rule that the committe tries to keep conferance foes out of the same bracket if possible. The tourney also tries to keep teams regional so the best #1 seeds stay close to home. That puts Syracuse, Kentucky, and Kansas in regions close to home. Since there is no dominate team out West this year the 4th #1 seed ends up out West (Carolina or Duke). Then you do the same with the #2 seeds. Mizzou would likely be a highly ranked number two and should end in the midwest, but If KU is a #1 in that bracket Mizzou won't be a #2 in that bracket. With Mizzou being essentially homeless and the furthest west of the #2's they go West.
Now if If KU would lose to a team in the conferance final other than MU and Carolina/Duke don't meet for the ACC championship I could see a possibility of KU retaining a #1 seed, but out West. Then maybe MU ends up as #2 seed in St. Louis.
Off course this can all change with a couple losses from each team....that is why I love this time of year.
