Under the new format, the four lowest-seeded teams will play "First Four" games, with the winners advancing as sixteen seeds to play two of the top-seeded teams. "The other two first four games will match up the last four teams to receive at-large bids."
This is why Tennessee and Iowa are in play-in games. Still don't think it's fair. An automatic bid will be in a play-in game if they are one of the bottom four seeds.
Sorry but if Tn wins they do NOT advance as sixteen seeds to play two of the top-seeded teams.
The Iowa/Tn winner will play #6 UMass
The NCST/XAV winner will play #5 SIU.
It's the other two winners that will move to #16http://espn.go.com/mens-college-basketball/tournament/bracket
