Of the four teams in Philadelphia, only North Carolina and Wisconsin would provide a regional final that wasn't a rematch from a regular season matchup. That could be really fun.
You don't need extra storylines for Sweet 16 matchups, but the East Regional in Philadelphia will provide plenty when it gets going Friday night.
In the opening matchup, you'll have two programs that are among college basketball's bluebloods -- having combined for 10 total titles. But you don't need the history to make the matchup compelling. You could easily argue North Carolina and Indiana turned in the best performances of any two teams in the opening weekend of the tournament.
