The NCAA has released the brackets to the NCAA Championships, and Mizzou received a #4 seed, meaning they were within the top 16 nationally.
They will take on Evansville (13-4-2) in the 1st round, and would meet the winner of Memphis (15-4-2) and Illinois (11-8-1). If they come through, they would take on (likely) #1 seed North Carolina, who I believe was either 2nd or 3rd overall, and likely in North Carolina.
Other Big XII teams to make the tourney were #3 seed aTm (taking on Texas St.), #4 seed Okie State (taking on the STAGS OF FAIRFIELD), #4 seed CU (taking on South Dakota State), UT (taking on Washington St, and in with #2 seed Portland) and kU (taking on Denver and in the same bracket as #1 seed and #4 overall Stanford)
