The system seems to work but i am takingthe difference in ranking position! Teams most likely to lose like Dartmouth are over 1100 spots aart! ie today unc-g is a system play bc w. car is ranked 180! But unc-g is ranked 291! 111 spots apart!!! +11 going to be hard to stay within the number!!!
On the other hand # 239 Bradley at #231 S. IL is 8 spots apart and the spread is +5.5! They will most likely cover or even win outright!
