Or we could look at national rankings. Even throwing out the two outliers—Contortionists and Unrepentant Gunners—the Big 8 comes out with an average NR of ~51, while the Great 8's average is ~35. Again, removing the two outliers, the difference in median ranking of the two leagues is even more pronounced: Big 8's median is 59 while the Great 8's is 32. I guess you can draw your own conclusions:-)
