They did the one player from each team thing at the Houston Regional this year, so it was odd to not see them do it at the final four. Maybe that stupid garbage montage thing that CBS wanted to do took precedent?
On the other hand, I don't mind introducing the whole team at once. That is how it is done all season and it lets the team do whatever goofy team thing they do during player intros.
I thought the Memphis 'explosion' bit was pretty funny. And they did that then went and shook hands at center during the regionals. I also though it was strange that Nantz did the intros instead of the pa guy.
