You're a little wrong here. Iowa and Xavier would've been the ones left out. But who cares, Go Vols!
Actually, he is correct. The other two play-in games had four automatic qualifiers in them. All 16 seeds who won their respected conference tourney. The additional 4 teams to make it 68 instead of 64 were the Vols, Iowa, NC State, and Xavier. That is why we are considered the last 4 in. I guess there is an argument that we may have been the 64th team and Dayton would have been left out since there was talk that they weren't in the play-in games because they were played in their home town, but there is no proof of that. But, again, who cares! We made it in, and we are showing the nation that we deserved to be here! GBO!
