re: SEC power rankings after week 5:

I mean there is no direct comparison but no sure why Tenn would deserve to be higher than Ole Miss.
Transitive property is almost impossible, but in this case it's all we have

Tenn barely beat Pitt even after the Pitt starting QB got hurt
Ole Miss beat Georgia Tech 42-0
Georgia Tech beat Pitt at Pitt

Tenn barely beat Florida at home by giving up over 30 points to an awful offense
Kentucky beat UF at UF only allowing 16.
Ole Miss beat Kentucky

So not really sure why Tenn gets the nod
