These things are fun but all dreams at this point. Virginia is likely to lose several games such as at Duke, UNC, and may lose a couple times on their home court as well. Personally, the only 2 teams that I see as threats are Duke and Wisconsin.
Wisconsin plays a ball control offense and can be a real challenge if they keep the score close and foul near the end guys like WCS, Johnson, even Andrew.
Duke is a hot and cold team. If they are hitting a lot of 3's, they are tough because they also get the benefit of all the ref's calls.
Otherwise, it was be a huge upset for another team to beat Kentucky by tourney time assuming everything else remains as is.
