I don't think BPI should be used to seed teams, but I understand it's usefulness. I'm sorry that so many on this board still don't seem to understand what it is showing, but it is useful. I guarantee it will predict several of the upsets that happen in the tournament. Why? Because it shows that a team like osu, or Baylor, WHEN they play well, can beat a lot of teams that had better seasons.
But again, I don't think you can seed teams based on that, b/c actual game results, wins and losses, has to dictate that.
