I thought we did it back in 2011. Oregon, Bama, Ark, Georgia. I think there might have even been one more. I know our OOC schedule that year was ridiculous. I think all but just a couple of teams we played were ranked and of those, 4 or 5 were top 10. If we could have just sealed the deal, then they would have a great argument for being the best team in NCAA history.
Oregon, Alabama and Arkansas were all top 5 teams and I do believe we are the only team ever to do that. I need to research the Georgia game. Maybe they don't count the CCGs. UPDATE: Georgia was ranked #12 in the AP when we faced them in 2011.
