At this point they have. Kentucky and Syracuse are locks as of right now. Missouri is more than likely a good bet unless they crash and burn the rest of the way. One of UNC and Duke will probably play into the last spot.
OSU and Kansas aren't out of the equation, but they would need others to lose a couple games.
Looking at their Schedule I think they lose one more in the regular season and another in the BiG tourney. They have consstently struggled with the top BiG teams all season. They are at 5 losses now and I think it will be 7 by the time they pick the NCAAT. Could possibly be a three seed.
SU and UK are locks as one seeds right now. I also think Mizzu is close to a lock.
That would be fine for me as I don't want to play Duke before the final four. I think Ohio State would struggle against our zone their offensive effort was awful against Michigan last night. They went 4-5 possesions in a row without giving Sullinger a touch in the post. Craft is a human gnat and would generate turnovers but Ohio only has 2 shooters Buford and Smith Jr. who can be cold I think we would beat Ohio in the Elite Eight in Boston.
My current projections
SU-1 East
Ohio- 2 East
Kentucky-1 South
North Carolina-2 South
Missouri - 1 Midwest
Michigan State- 2 Midwest
Duke- 1 West
Kansas-2 West
