Fair SEC match ups?

I really would be interested in two things.

One, how many times are SEC teams matched up against teams that are a higher seed? In other words, if SEC teams always play a lower ranked team wouldn't that skew the records?

I honestly don't know if the SEC usually plays lower ranked teams or not, but it is never mentioned in the debates.

Also, how many times does the SEC play away from it's home? Michigan playing Florida in Florida, seems a distinct advantage to Florida, just like USC playing any Big Ten team in the Rose Bowl is an advantage, though to be honest it would not have mattered where Illinois played yesterday.

Thank you,
