On Lunardi's most recent bracket we are still a 3 seed, currently sitting in the East region with Syracuse on the top line and Duke as the 2. Vanderbilt is the 6 in our pod, which I hope changes between now and the tournament, since they will have a huge advantage in the Nashville location he assigns us to.
Assuming we can get through Northwestern to the Semis of the BTT and (probably) another game against Ohio, I don't see how we fall below a 3. Also, assuming Ohio and MSU are pretty solid 2 seeds, the tournament committee won't put us in the same region so there is no intra-conference game in the Sweet 16. My point here is that if Duke stays as a 2 seed, we have about a 50-50 chance of seeing them in the Sweet 16, if both teams make it through. I think fans of both schools would love another game, and we will want to avenge the loss in the tournament last year and in Hawaii at the beginning of the season this year.
Obviously it's a long week between now and Selection Sunday, and things will change. But, this might be an intriguing story to watch as it gets closer.
