so 0-7 against the ranked over the last 10 seasons...

but none of 'em at the Stu. They don't list seasons any further back, but any further back, and it wouldn't have been at the Stu anyway
this is just going by what is listed on the schedule/results page, without checking them against the polls at the time or anything like that... and I'm not sure which poll they're using, or if any would have been left out from the other poll
