It was pretty clear that Purdue, Houston and UConn had wrapped up 1 seeds going into the week. So, the drama became who would take the last #1 seed. The polls and the regular season championships of the major conferences suggested it was a race between #4 North Carolina, #5 Tennessee and #6 Arizona.

Well – the Tar Heels handled their business in the ACC semi-finals – fighting off a desperate Pitt team for a 72-65 victory. But with Tennessee losing by 17 in the SEC quarterfinals to Mississippi State and Arizona losing by 8 in the Pac 12 semifinals to Oregon, the other two leaders will be sitting out the rest of the weekend.

And considering that UNC also beat Tennessee in the regular season, I suspect that ends the conversation. The Lunatic is predicting that the Tar Heels will join Houston, UConn and Purdue on the top line. I am not sure how I will rank order the Cougars, Huskies and Boilers – but I am not sure that matters to his bracketology – a 1 seed is a 1 seed.

It does look like the bubble is getting tighter and tighter, as bubble teams fight their way to their conference championship games. It should be a really interesting Selection Sunday.
