Curious were you get your numbers?
I was just curious were you get your numbers of 63-45-2 vs the Big-10?
I've looked at the same statistics & my numbers show they have played many more games. I looked at all the numbers as well as some other websites & the census on the record is 91-86-6 with a slight edge to the Big-10.
Of course if you break it down team by team you will see that the bottom teams of each conference have played the top teams of the other conference many more times. Example Vandy vs Michigan (met 11 times) rather than say Florida vs Michigan (met 1 time).
I was just wondering if your looking at only certain games like just regular season games & not bowl games?
