You and
@Kaizen and
@mbr33ct are of course 100% right. It's like saying "NC state's win over SC is not that big a deal - they beat a team not in the top 4". Um sorry, but SC was ranked #1 at the time, whether you think they were the #1 team or not.
Frankly I can't believe we are actually debating this. USF beat the team who was ranked #6 at the time and that's how the voters will look at that win. It's always been that way. It probably always will be that way. You can argue that Mississippi State is better or worse than their ranking at any time this season and whoever they play, that argument is completely irrelevant.
More than that, it's flat out wrong. The QUALITY of their win is based on beating the #6 team in the country. Period. It's not the least bit debatable as far as the ranking services go.
Hope that cleared it up...
