ESPN Stats and Information
Syracuse is currently the 1st team out if you seed the tournament according to Strength of Record which is a measure of who "deserves" to be in the tournament as things currently stand. Their Strength of Schedule is 31st, not too bad, but for comparison, TCU's SOS is 32nd and they are 17-11 while Syracuse is 17-12. TCU is the last at-large deserving according to SOR. That one extra loss is the difference.
