I wish that margin of victory mattered for seeding. Losing by 20 to a #1 ranked team at home is a LOT different that going to the #1 team's place and losing by 2.
Duke played the #1,#2,#3 RPI teams 6 times and lost 5 times by margins of 3, 7, 12, 12 and 17 points and won one of the games by 17 points. That's pretty close on most of them.
Duke's double digit losses were vs. #2, at #3 and vs. #3 RPI, and then a weird loss in the CT to #74.
So 9 of the 13 losses were by 1-9 points.
